Operator's Manual Part I: Introduction to Remote Control About This Manual This manual includes a complete list of the command you’ll need to perform most WaveAce® 1000 and 2000 operations remotely. Part I is an introduction to remote control and remote command syntax. Part II lists all supported command headers with valid data parameters and values. About Remote Control WaveAce 1000 and 2000 series oscilloscopes can be controlled remotely through a USBTMC or TCP/IP (LAN) interface.
WaveAce Remote Control Remote Control Through USB The USB interface is standard on every WaveAce oscilloscope. The rear panel USB port is the remote control interface. 1. Attach a USB A/B cable from the USB-B port on the rear panel of the scope to a USB-A port on the controller computer. 2. Install NI-VISA on the controller machine. NI-VISA contains the USB drivers needed to form the interface between the oscilloscope and the controller. NI-VISA can be downloaded free from www.ni.com/visa.
Operator's Manual Remote Control Through LAN WaveAce 2000 series oscilloscopes have a standard LAN connection port for remote control that utilizes Teledyne LeCroy's VICP protocol for transmitting messages. This protocol emulates IEEE 488.2 (GPIB) and includes operation bits corresponding to SRQ, EOI, Clear, and others in a header that is defined by the VICP protocol. The WaveAce must be assigned a static IPv4 address for remote control; do not use an address from the DHCP pool.
WaveAce Remote Control 3. Enter an IP Address, Subnet Mask, and Gate Way. Enter values by selecting each segment and turning the Adjust knob until the desired number is reached. Press the top soft key to jump to the next field or press the Adjust knob to tab to the next segment of the current field. Leave DHCP disabled. Program Messages Program messages are composed of commands or queries separated by semicolons and ending with a terminator: ; . . . . .
Operator's Manual The header path normally consists of an abbreviated path name followed by a colon ( : ) immediately preceding the command header.
WaveAce Remote Control Character Data These are simple alphanumeric words or abbreviations indicating a specific action. In commands where you can specify many parameters, or where not all parameters are applicable at the same time, the format requires pairs of character data values. The first value names the parameter to be modified, while the second gives its value.
Operator's Manual Block Data These are binary data values used to transfer waveforms from the oscilloscope to the controller using the WAVEFORM command/query. Buffer size limitations apply to block data: If data exceeding the oscilloscope’s 512 byte input buffer limited is received, the excess is discarded until a terminator (delimiter) is detected. If data exceeding the output queue is transmitted, commands that are not interpreted and excess data are discarded.
WaveAce Remote Control The oscilloscope follows stricter rules for response messages than for program messages: Program messages may be in upper- or lower-case characters, but response messages will always be upper-case. Program messages may contain extraneous spaces or tabs, but response messages will not.
Operator's Manual (Bit 7) plus 32 (bit 5). See the table with the ESR command description in Part Two for the conditions corresponding to the bit set. The Power ON bit appears only on the first *ESR? query after power-on (since the query clears the register). You can determine this type of command error by reading the CMR bit with CMR?. It is not necessary that you read/ clear this register in order to set the CMR bit in the ESR on the next command error.

Operator's Manual ACQUISITION - WAIT Description The WAIT command prevents your instrument from analyzing new commands until the current acquisition has been completed. The optional argument specifies the timeout (in seconds) after which the scope stops waiting for new acquisitions. If is not given, or if = 0.0, the scope waits indefinitely.
WaveAce Remote Control CURSOR - CURSOR_MEASURE, CRMS Description The CURSOR_MEASURE command specifies the type of cursor or parameter measurement to be displayed, and is the main command for displaying parameters and Pass/Fail. Use it to turn on/off cursors. The CURSOR_MEASURE? query indicates which cursors or parameter measurements are currently displayed. Command Syntax CuRsor_MeaSure := {HREL, VREL} Where: HREL - Horizontal relative cursors. VREL - Vertical relative cursors.
Operator's Manual CURSOR - CURSOR_SET, CRST Description The CURSOR_SET command allows you to position any one of the independent cursors at a given grid location. When you are setting a cursor position, you must specify an active trace relative to which the cursor is positioned. The CURSOR_SET? query retrieves the current position of the cursor(s). The values returned depend on the grid type selected: HREF Horizontal Cursor A VREF Vertical Cursor A. HDIF Horizontal Cursor B VDIF Vertical Cursor B.
WaveAce Remote Control CURSOR - CURSOR_VALUE?, CRVA? Description The CURSOR_VALUE? query returns the values measured by the specified cursors. The PARAMETER_VALUE? query is used to obtain measured waveform parameter values. The keyword ALL should not be used; neither should multiple keywords. If they are used, the word UNDEF is returned. For the CRVA? query to work, the specified trace must be visible, and the current cursor mode must be the same as in the query. If it is not the same, UNDEF is returned.
Operator's Manual CURSOR - PARAMETER_CUSTOM, PACU Description The PARAMETER_CUSTOM command controls the placement of custom cursors and can also be used to assign any parameter for histogramming.

Operator's Manual Decoding Floating Point Numbers Single precision values are held in four bytes. If these are arranged in decreasing value order we get the following bits: bit 31, bit 30, bit 29, bit 28 . . . . . bit 3, bit 2, bit 1, bit 0 NOTE: If the byte order command CORD is set for low byte first, the bytes as received in a waveform descriptor are received in reverse order. However, within a byte the bits keep their order, highest at the left, as expected.
WaveAce Remote Control In a way not following the byte boundaries, bits are then segregated as follows: 31, 30, 29 . . . . 24, 23, 22, 21 . . . . 2, 1, 0 Sign exponent bits fractional bits bit 0.5, 0.25, 0.125 . . . The sign bit s is 1 for a negative number and 0 for a positive number, so it is easy to construct the sign from this: S = (-1)^s The 8 exponent bits have the following values: bit 2 - 1, which is 255. 127 is then subtracted from this value e creating a range from -127 to +128.
