53210A Measurements 3
Keysight 53210A User’s Guide 95
The commands used to make frequency measurements are:
MEASure:FREQuency? [{<expected>|MINimum|MAXimum|DEFault}
[,{<resolution>|MINimum|MAXimum|DEFault}]][,<channel>]
CONFigure:FREQuency [{<expected>|MINimum|MAXimum|DEFault}
[,{<resolution>|MINimum|MAXimum|DEFault}]][,<channel>]
– expected is the expected input signal frequency. resolution is the desired
measurement resolution in hertz. The parameter ranges are:
expected (channel 1): 0.1 Hz - 350 MHz (default = 10 MHz)
expected (channel 2 Option 106): 100 MHz - 6.0 GHz (default = 500 MHz)
expected (channel 2 Option 115): 300 MHz - 15 GHz (default = 500 MHz)
resolution (all channels): 1.0E-15* expected to 1.0E-5* expected
(default
resolution corresponds to a 0.1s gate time)
–
channel is counter channel 1 or 2 specified as (@1) or (@2).
Frequency Measurement Examples
// using MEASure? - measure 20 MHz signal with 0.1 Hz
// resolution
*RST // reset to start from known state
MEAS:FREQ? 20E6, 0.1, (@1)
-----------------------------------------------------------------------
// using CONFigure - measure 20 MHz signal with
// 0.1 Hz resolution, take 10 readings
*RST // reset to start from known state
CONF:FREQ 20E6, 0.1, (@1)
SAMP:COUN 10 // take 10 readings

trigger (sample count).
