◼
Frequency setting
Either k (kilo: 10
3
) or m (milli: 10
−
3
) can be used as the multiplier suffix for the upper limit
frequency and lower limit frequency values in the oscillator’s frequency and sweep measurements.
The unit for each suffix is Hz.
Example: FREQ:SWE:MAX 100 kHz

[:SOURce]:FREQuency[:IMMediate]?
Description Sets or queries the oscillator frequency.
Parameter <freq_current> Oscillator frequency
format <NR3>, range 0.10E
−
03 to 100.00E+03 [unit: Hz]
Setting example FREQ 1000
Response <freq_current>
Query example FREQ?
Response example 1.0000E+03
[:SOURce]:SWEep:MEASure <measure_operation>
[:SOURce]:SWEep:MEASure?
Description Specifies a sweep or spot measurement or queries its status.
Parameter <measure_operation> Measurement operation
format <CRD>, range STOP | SPOT | UP | DOWN
