Syntax
:MEASure:FREQuency?
Function
The query returns the frequency measurement value in the form of
scientific notation such as +8.485240e-05, the unit is Hz.
40. :MEASure:FREQuency
Syntax
:MEASure:FREQuency {0|1|2|3|4|MIN|MAX|DEF}
Function
Sets the voltage range of input signal for frequency measurements.
Explanation
 For meanings in each range, please refer to the
“Explanation” in :MEASure:VOLTage:AC.
 The frequency ranges from 3 Hz to 300 kHz.
 The “DEF” is 2.
Example
Setting the voltage range of the frequency measurement to
maximum:
:MEASure:FREQuency 4 or
:MEASure:FREQuency MAX
41. :MEASure:FREQuency:RANGe?
Syntax
:MEASure:FREQuency:RANGe?
Function
Queries the AC voltage range currently used by frequency
measurements.
The query returns 0, 1, 2, 3 or 4.
42. :MEASure:FREQuency:DIGIt
Syntax
:MEASure:FREQuency:DIGIt?
:MEASure:FREQuency:DIGIt {INC|DEC|5|6|7}
Function
Sets the display digit for frequency measurement values.
The query returns 5, 6 or 7.
Explanation
Refer to the “Explanation” in :MEASure:VOLTage:DC:DIGIt.
Example
Setting the display digit to 7:
:MEASure:FREQuency:DIGIt 7
Decreasing the display digit by one bit:
:MEASure:FREQuency:DIGIt DEC
43. :MEASure:PERiod?
Syntax
