7 Error Messages Errors are retrieved in first-in-first-out (FIFO) order. The first error returned is the first error that was stored. Use :SYST:ERR? to read errors. When user has read all errors from the queue, the error queue becomes empty and any error query will return +0, “No error”. The MODEL 1105 beeps once each time an error occurs. Should more than 29 errors have existed, the last error stored in the queue (the most recent error) is replaced with -350, “Queue overflow”.

D. Remote Interface Reference D.1 Introduction to the SCPI Language SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command language designed for test and measurement instruments. Refer to “Simplified Programming Overview,” for an introduction to the basic techniques used to program the universal counter over the remote interface. SCPI commands are based on a hierarchical structure, also known as a tree system.
SENSE, sens, and Sens are all acceptable. Other forms, such as SEN and SE, will generate an error. A vertical bar ( | ) separates multiple parameter choices for a given command string. Triangle brackets ( < > ) indicate that you must specify a value for the enclosed parameter. For example, the above syntax statement shows the range parameter enclosed in triangle brackets. The brackets are not sent with the command string. You must specify a value for the parameter (such as "INPut:COUPling AC").
Use a colon and a semicolon to link commands from different subsystems. For example, in the following command string, an error is generated if you do not use both the colon and semicolon: :DISP:MENU OFF;:CALC2:LIM:DISP NUMBER Querying Parameter Settings You can query the current value of most parameters by adding a question mark (?) to the command.
keyword is separated from the first parameter by a blank space. Use a semicolon (;) to separate multiple commands as shown below: *RST; *CLS; *ESE 32; *OPC? SCPI Parameter Types The SCPI language defines several different data formats to be used in program messages and response messages. Numeric Parameters Commands that require numeric parameters will accept all commonly used decimal representations of numbers including optional signs, decimal points, and scientific notation.
DISPlay:TEXT “CALC2” D.2 Command Reference :ABORt Aborts any measurement in progress as quickly as possible. Notes When this command is sent while the measurement cycle is idle (:INIT:CONT OFF and pending operation flag is false), it is ignored. When this command is sent while a single measurement is in progress (:TRIG:COUN:AUTO OFF or :CALC3:AVER OFF, :INIT:CONT OFF, and pending operation flag is true), the measurement will be aborted and pending operation flag set false.
When using ASCii format, numeric data is transferred as ASCII bytes in format. The number of significant digits will range from 1 to 15, depending on the measurement resolution. Only significant digits will be returned. If there is no valid result, error -230 will be generated and 9.91E37(Not A Number) will be returned. If Totalize or Voltage Peaks are chosen, error 0221 will be generated and 9.91E37(Not A Number) will be returned.
Note The recalculation is done automatically when any change is made to any of the :CALCulate[1|2] commands when :CALC:IMM:AUTO ON. :CALCulate[1]:IMMediate? Queries the results of the new calculation. Note As the commands INIT:CONT OFF and CALCulate[1]:IMMediate:AUTO OFF are inputted, the command :CALCulate[1]:IMMediate? is just valid. :CALCulate[1]:IMMediate:AUTO Sets if the re-calculation will automatically be done whenever there’s any change made to any of the :CALCulate[1|2] commands.
A sequence of ASCII-encoded bytes(“SENS”*SCALE+OFFSET) terminated by a new line and EOI. Note It should be the last query in a terminated program message or error-440 will be generated. :CALCulate[1]:MATH[:EXPRession]:NAME SCALE_OFFSET Or :CALCulate[1]:MATH[:EXPRession]:SELect SCALE_OFFSET Defines the name of the expression used in mathematic operation. Return A sequence of ASCII-encoded bytes:SCALE_OFFSET. :CALCulate[1]:MATH:STATe Enables or disables the mathematic operation.
:CALC2:LIM:FCO :CALC2:LIM:PCO :CALC3:… Note The re-calculation is done automatically when any change is made to any of the :CALCulate[1|2] commands when :CALC:IMM:AUTO is ON. :CALCulate2:IMMediate:AUTO Sets if the re-calculation will automatically be done whenever there’s any change made to any of the :CALCulate[1|2] commands. When it is set to OFF, the :CALCulate[1|2] command produces new results when the command is executed, even when new data is not acquired.
This will be set to ON after the counter has been turned off or a remote interface reset. When this is set to ON, the following will be done whenever :INIT[:IMM] or :INIT:CONT ON is executed: The limit data gets cleared. The :CALC2:LIM:FAIL, :CALC2:LIM:FCO and :CALC2:LIM:PCO information gets cleared. The Limit-Detect output of the RS-232 connector is set to the in-limit voltage level.
If the current measurement function is Totalize or Voltage Peaks, a “0” will be returned and error -221 will be generated. :CALCulate2:LIMit:FCOunt:LOWer? Queries the number of the measurement that fails the lower limit test. Return Numeric data transferred as ASCII bytes in format. Notes If the limit test is off, a “0” will be returned and error -221 will be generated. If there is no valid measurement result, a “0” will be returned and error -230 will be generated.
generated. If the current measurement function is Totalize or Voltage Peaks, a “0” will be returned and error -221 will be generated. :CALCulate2:LIMit:PCOunt[:TOTal]? Queries the total number of measurements that pass the limit test. Return Numeric data transferred as ASCII bytes in format. Notes If the limit test is off, a “0” will be returned and error -221 will be generated. If there is no valid measurement result, a “0” will be returned and error -230 will be generated.
A fail will be returned if the result is less than the lower limit, but when the result is equal to the lower limit, the counter will not report a fail. Notes The lower limit will be set to 0 after the counter has been turned off or a remote interface reset. Setting a new lower limit will clear the limit counts (:CALC2:LIM:FCO, :CALC2:LIM:PCO). If the limit testing is on (:CALC:MATH:STATe ON), user should consider the scaled and offset results when specifying the limit.
digits range from 1 to 15, depending on the resolution. Notes The statistics operation should be enabled (:CALC3:AVER[:STATe] ON ) before using this command. If not, Not A Number 9.91E37 will be returned and error -221 will be generated. The result is separated by commas, and the display order is mean value, standard deviation, minimum value and then maximum value. If there is no valid result, Not A Number 9.91E37 will be returned and error -230 will be generated.
Return Numeric data transferred as ASCII bytes in format. Notes If the statistics operation is not enabled (:CALC3:AVER[:STATe] OFF, error -221 will be generated. If the current measurement operation is Totalize or Voltage Peaks, 0 will be returned and error -221 will be generated. :CALCulate3:AVERage[:STATe] Sets or queries the statistics operation state. Return A single ASCII-encoded byte. 0 means OFF and 1 means ON.
significant digits will range from 1 to 15, depending on the resolution. Notes Be sure to enable the statistics operation before query the result. If the statistics operation is not enabled (:CALC3:AVER[:STATe] OFF), or the current measurement function is Totalize or Voltage Peaks, Not A Number 9.91E37 will be returned and error -221 will be generated. If there is no valid result, Not A Number 9.91E37 will be returned and error -230 will be generated.
(:CALC2:LIM:FCO, :CALC2:LIM:PCO). When the display is not able to show all of the significant digits of this value, the displayed value is different from the actual value because the displayed value has been rounded. But if you press ENTER while the number is still in display, the actual value will be updated to the value shown. :CALCulate3:LFILter:UPPer[:DATA] [HZ|S|DEG] Sets or queries the upper limit in statistics operation. The resolution is 11 digits and the range is from -9.
It will be returned to 0 after the counter has been turned off or a remote interface reset. When this is on, only the measurements (scaled and offset when math is on) within limits will be used in statistical calculation. :CALCulate3:PATH? Queries the order in which CALCulate3 sub-blocks are to be processed. Return A sequence of ASCII-encoded bytes: LFIL, AVER. Notes For the counter, this sequence is fixed to be LFILter followed by AVERage.
Notes The security state is stored in non-volatile memory and is unaffected by power-on, save/recall or *RST. The security code is set to 1105 when the Counter is shipped from the factory. If users forget the security code, they can use the :CALibration:SECurity:CODE:RESet command to recover to the default condition.
A string with the form of “ [,]” is returned. If there is not any specification before this query, an empty string is returned and an error -221,"Settings conflict" is generated. The response is unaffected by *RST, recall, or [:SENS]:FUNC. Note Refer to (The Command :MEASure?) later in this section for the descriptions of the and the for each function.
Return A single ASCII-encoded byte. 0 means that the result display is in enabled and 0 means that the menu display is enabled. Notes The state of the display will be set back to OFF which means that the menu display is disabled and the result display is enabled after *RST command. Use :SYST:KEY command or the front panel key to display the menu. This value is unaffected by save&recall.
A sequence of ASCII-encoded byte: COMM or DPO. Note This value is stored at non-volatile memory, so it will not change after the counter has been turned off, or after *RST command or save&recall. :FETCh[[:SCALar]:]? This command queries the measurement taken by the command :INItiate (or :MEASure query or :READ?). This command is the generic form of the Commands :FETCh?.
first. Note Sending this command while a measurement is in progress will hold off further commands from being executed until the current measurement completes. However, you can use Device Clear or power-on to cancel this hold-off effect. :FORMat[:DATA] ASCii|REAL Sets or queries the format type of the data. When choosing ASCii type, numeric data is transferred as ASCII bytes in format. The numbers are separated by commas as specified in IEEE488.2. When there is no response data, Not A Number 9.
Return A single ASCII-encoded byte. 0 means AUTO OFF and 1 means AUTO ON. Note This will be set back to AUTO OFF after *RST command. :INITiate:CONTinuous Sets or queries the enable for initiating measurements continuously. When the CONTinuous is set to ON, the measurements are initiated continuously, when the CONTinuous is set to OFF, the counter does not issue any measurement until it receives :INITiate[:IMMediate] command or CONTinuous is set to ON. Return A single ASCII-encoded byte.
The beginning of the first measurement caused by setting :INIT:CONT ON sets the pending Operation Flag to true. The pending Operation Flag is set to false by aborting of a measurement, or by the completion of the last measurement after :INIT:CONT is set to OFF. When the measurements are being made continuously, :ABORt command will terminate the measurement in progress, but does not change the value of :INIT:CONT.
receives :INIT[:IMM]. When :CALC2:LIM:CLE:AUTO is ON and whenever the counter receives :INIT:CONT ON command, it : o Invalidates the limit data, o Clears the pass and fail counts (:CLAC2:LIM:FCO and :CALC2:LIM:PCO) in the limit testing. o Sets the Limit-Detect output to the in-limit voltage level. When [:SENSe]:EVEN:LEV[:ABS]:AUTO is ON and :INIT[:IMM] command is sent, the counter issues an auto-trigger on the source.
Sets or queries the state of the low-pass filter. Return A single ASCII-encoded byte. 0 means OFF and 1 means ON. Note This will be set to OFF after *RST command :INPut[1|2]:FILTer[:LPASs]:FREQuency? Queries the cut-off frequency of the low-pass filter. Return Numeric data transferred as ASCII bytes in format with six significant digits. A value of 100E+3 is returned. :INPut[1|2]:IMPedance [OHM] Sets or queries the input impedance. It is either 50Ω or 1MΩ.
Numeric data transferred as ASCII bytes in format with six significant digits. The value returned is 50. The Commands :MEASure? The command :MEASure is the simplest way to make a measurement. It configures the counter, initiates the measurement and queries the result all in one command. :MEASure[:SCALar]:? [,] The above command is the generic form of the :MEASure? Commands.
:MEASure[:SCALar][:VOLTage]:FALL:TIME? [ [,upper_reference>]][,(@1)] Sets the measurement arming to “auto” and measures Fall Time with the specified parameters. The and are used to specify the lower and upper points on the falling edge of the input signal. They can be specified as either a percentage or an absolute voltage. The and are used to configure the trigger setting.

Return Numeric data transferred as ASCII bytes in format, which is 21. The response is one greater than the maximum which can be sent as a parameter to the *SAV and *RCL commands. :READ[[:SCALar]:]? The command is usually used with a :CONFigure command to make measurements like Command :MEASure?. User can specify individual setting for their measurements by adding setting specification commands between them. This command is the generic form of the Command :READ?.
Queries the current measurement results of the :SENSe commands (no scale or offset applied). Return Result is formatted according to :FORMat[:DATA] ASCii|REAL command. Notes If using the ASCii format, numeric data is transferred as ASCII bytes in format. The number of significant digits ranges from 1 to 10 depending on the resolution. If there is no valid measurement result, Not A Number 9.91E37 will be returned and error -230 will be generated.
Return The “100”, “50” or “0” PCT is returned. Note As the command *RST is executed, the noise immunity will be set to 50 PCT. [:SENSe]EVENt[1|2]:LEVel[:ABSolute] [V] Sets or queries the level of the center of the hysteresis window. The range is -5.125 to 5.125 volts for X1 attenuation and -51.25 to 51.25 volts for X10 attenuation. The resolution is 0.0025V for X1 attenuation and 0.025V for X10 attenuation.
Sets or queries the percentage of the peak-to-peak range of the signal at which the instrument automatically triggers. The range is from 0 to 100 PCT, and the resolution is 10 PCT.

Before the “auto” totalize measurement is terminated, no totalize result will be available. [:SENSe]:TOTalize:ARM:STOP:TIMer [S] Sets or queries the gate time in arming Totalize measurements. The range is 1E-3 to 1,000 seconds and the resolution is 0.01E-3 seconds.
A USB or DB9 message will be returned. Note As the command :SYSTem:COMMunicate:SERial:SOURce USB is executed, users can’t do the remote control via USB excluding LAN or GPIB. :SYSTem:COMMunicate:SERial:CONTrol:DTR OFF｜LIMit Sets or queries the hardware pacing scheme. The parameter LIMit can be set by the ｜ command :SYSTem:COMMunicate:SERial:SOURce USB DB9. As the command is set to OFF, users can’t use the Output function of the Limit PASS/FALL.
:SYSTem:KEY This command simulates the pressing of a front-panel key. The parameter is a key code number. The following table shows the keys and their corresponding number codes. This command places an entry in the Key Queue just like the real pressing of a key on the front panel. The maximum capacity of the key queue is 500. Return Numeric data transferred as ASCII bytes in format. The number returned represents a key last pressed in the front panel.
:SYSTem:KEY:LOG? Queries all the entries in the Key Queue. Return Numeric data transferred as ASCII bytes in format. A “-1” is returned when the queue is empty. Each Key Code number is separated by a comma. The entries are in a last-in, first-out order. The maximum number of key codes is 500. Each key code has a range of 1 to 10. Note The Key Queue will be empties after the counter has been turned off or after a *RST command. Save/recall operation does not apply on this value.
I/O mode is compatible. ｜COMPatibility :SYSTem:UTILity:IO:MODE NATive To set and query the IDN string, the NATive can be selected for default, and the COMPatibility can be selected for user definition. Return A sequence of ASCII-encoded bytes: NAT or COMP. Note As the command *RST is executed, the NAT will be set. The Commands :TRACe These commands are used to specify and query the scale and offset values. :TRACe:CATalog? Queries the names of the constants the counter uses.
Return The format of the response is according to the specification made in :FORMat[:DATA] ASCii|REAL command. If using the ASCII format, the numeric data is transferred as ASCII bytes in format with eleven significant digits.
:TRIGger:COUNt:AUTO Sets or queries the control over the number of measurements taken when :INITiate[:IMMediate] command is sent. With this OFF, the :INIT[:IMM] initiates one measurement.
This command does not clear saved settings or any data memories. This command will clear any displayed error messages. *DDT This is a Define Device Trigger command. It sets or queries the command that the device will execute when it receives the IEEE 488.1 Group Execute Trigger (GET) interface message or a *TRG common command. The counter takes only the commands :INITitate[:IMMediate], :READ? and :FETCh? or otherwise error -224 will be generated.
Queries the Standard Event Status Enable Register. Return Numeric data transferred as ASCII bytes in format. Notes The Standard Event Status Enable Register is cleared and set to “0” after the counter has been turned off. This value is unaffected by save/recall and *RST. *ESR? Queries the Standard Event Status Register. This event register captures changes in conditions, by having each event bit correspond to a specific condition in the instrument.
counter has been turned off or upon the transition of the measurement cycle from measuring to idle. *OPC? A response is generated when the counter is placed in an idle state from a measuring state. This allows synchronization between a controller and the instrument using the MAV bit in the Status Byte Register or a read of the Output Queue.
