RF:SPECTRogra
m:STATE?
might return 0, indicating that the spectrogram
function is off.
RF:SPECTRogram:TIMe? (Query Only)
Queries the number of seconds in the spectrogram since continuous acquisition
started. The value returned is always <= 0.

RF:SPECTRogram:TIMe?
Examples
RF:SPECTR:TIME? might return -66.8174, indicating that there were
66.8174 seconds in the spectrogram since continuous acquisition started.
RF:SPECTRUMMode
When only the frequency domain waveforms are displayed (no time domain
waveforms), you can choose whether the MDO4000/B/C should use Triggered
mode or Free Run mode. (MDO3000 series models only use Free Run mode.)
When Triggered mode is selected, you can control all trigger settings, including
Normal and Auto triggering. When Free Run mode is selected, the oscilloscope
generates RF acquisitions as fast as possible. The default is
FREErun. (On an
MDO4000/B/C series model, in order to display only the frequency domain
waveforms, you need turn off all time domain waveforms, including channels1-
4, digital channels 0 - 15, buses, time domain math waveforms, time domain
reference waveforms, and any RF vs. Time traces.)
When the MDO4000/B/C oscilloscope displays both
time and frequency domain
waveforms, then the instrument’s trigger system is in control of the Triggered
mode and the RF acquisitions.
NOTE. Note: the Free Run spectrum mod
e is only possible when all analog and
digital channels are turned off.
Conditions
MDO4000/B/C models only.
