GRF-1300A User Manual and Teaching Materials
Set the amplitude and frequency of each point. Use the arrow
keys to move the cursor to each of the different points. Use the
same method is used to edit both the upper and lower limit
lines. Pass/Fail testing can be started after setting the limit
lines.
2. Use the remote commands to read back test results.
Manually setting the spectrum analyzer for testing can be
time-consuming. Here we will use remote commands to set
various parameters on the spectrum analyzer remotely. We
will briefly explain some of these commands below.
Frequency
Commands
meas:freq:cen? Return the center frequency in kHz.
meas:freq:cen Sets the center frequency, for
example:
meas:freq:cen_100_mhz
meas:freq:st? Returns the start frequency in kHz.
meas:freq:st Sets the start frequency, for example:
meas:freq:st_100_mhz
meas:freq:stp? Returns the stop frequency in kHz.
meas:freq:stp Sets the stop frequency, for example:
meas:freq:stp_100_mhz
Span
Commands
meas:span? Returns the frequency span settings.
meas:span Sets the frequency span settings, for
example:
meas:span:10_mhz
meas:span:full Sets the span to Full Span mode.
Amplitude
Commands
meas:refl:unit? Returns the reference level unit.
meas:refl:unit Sets the reference level unit.
Parameters: 1(dBm), 2(dBmV),
3(dBuV)
meas:refl? Returns the reference level in dBm.
meas:refl Sets the reference level in dBm. For
example: meas:refl:-30
