Frequency
>|VAR|
EXT1|EXT2|FMIN|FMAX}
:FREQuency:FUNCtion?
<Frequency>: 50|60|400
50(Hz): Fixed to 50 Hz internal frequency
60(Hz): Fixed to 60Hz internal frequency
400(Hz): Fixed to 400Hz internal frequency
VAR: Variable internal frequency
EXT1: External oscillator input
EXT2: External oscillator input (phase angle)
FMIN: Minimum scale value of the frequency
meter
