:COUNter:MEASure?
Syntax :COUNter:MEASure?
Description Query the measurement results of the frequency counter.
Explanation When the frequency counter is in the “RUN” or “SINGLE” state, send this command
to query the measurement values. When the frequency counter is in the “STOP”
state, send this command to query the measurement values of the last
measurement.
Return Format The query returns a string consisting of 5 parts (represent the frequency, period,
duty cycle, positive pulse width and negative pulse width respectively) separated by
commas. Each part is expressed in scientific notation and contains 10 effective bits,
for example,
2.000000000E+03,5.000000000E-04,4.760800000E+01,2.380415000E-04,
2.619585000E-04 (represents the measurement result is 2kHz frequency, 500us
period, 47.608% duty cycle, 238.0415us positive pulse width and 261.9585us
negative pulse width).
When the frequency counter function is disabled, the query returns
0.000000000E+00,0.000000000E+00,
0.000000000E+00,0.000000000E+00,0.000000000E+00.
Example :COUN:MEAS? /*Query the measurement results of the frequency counter and
the query returns 2.000000000E+03,5.000000000E-04,
4.760800000E+01,2.380415000E-04,2.619585000E-04*/
:COUNter:SENSitive
Syntax :COUNter:SENSitive {|MINimum|MAXimum}
:COUNter:SENSitive? [MINimum|MAXimum]
Description Set the trigger sensitivity of the frequency counter.
Query the trigger sensitivity of the frequency counter.
Parameter Name Type Range Default
Real 0% to 100% 25%
Explanation Relatively higher sensitivity is recommended for signal with small amplitude; low
sensitivity is recommended for low-frequency signal with large amplitude or signal
with slow rising edge to ensure more accurate measurement result.
Return Format The query returns the trigger sensitivity in scientific notation. The return value
contains 7 effective digits, for example, 3.000000E+01 (the trigger sensitivity of the
frequency counter is 30%).
Example :COUN:SENS 30 /*Set the trigger sensitivity of the frequency counter to 30%*/
:COUN:SENS? /*Query the trigger sensitivity of the frequency counter and
the query returns 3.000000E+01*/
