Frequency
Sets the frequency of Meters in the Frequency Scan measurement. For the Strip Chart measurement, this
key will set the frequency for both meters and strip chart. For APD measurement, this key is used to set the
frequency to perform Amplitude Probability Distribution. For Monitor Spectrum measurement, this key is
used to set the Center Frequency.

For the Frequency Scan measurement, when QPD, EMI Average or RMS Average detectors is
selected, you will see some delay for meters to reflect the new data due to filtering time. However, if
the change in the meters frequency is performed by knob or step keys, there will be no filtering time
added unless the change of the meters frequency has triggered other parameter changes.

Saved in instrument state.
For Frequency Scan and Strip Chart measurements, it depends on the instrument minimum
frequency.
For Frequency Scan, and Strip Chart measurements, it depends on the instrument maximum
frequency.

These commands above are included for ESU compatibility. The suffix 1|2 is irrelevant to the
measurement, they are added solely for remote language compatibility.
