COMMAND [:SENSe]:FREQuency:RESolution . . . <numeric_value>[<frequency_unit>]

Sets the resolution of the frequency measurement.

The allowable settings for <numeric_value> and <frequency unit> are:

1 Hz, 10 Hz, 100 Hz, 1 KHz, 10 KHz, 100 KHz, and 1 MHz.

COMMENTS • *RST: 1 Hz

• This command does not affect the unit multipliers of any measurement

queries.

COMMAND [:SENSe]:FREQuency:TRACking . . . <character_program_data>

Selects one of three signal-tracking modes (SLOW | FAST | OFF).

When TRACking is set to SLOW, the Counter applies two tracking

routines after each measurement; when it is set to FAST, it uses only

one tracking routine; when it is set to OFF, it does not use either of the

tracking routines.

COMMENTS • *RST: FAST

• The SLOW setting provides the most accurate signal tracking but

yields the smallest number of measurements in a given period of time.

• The FAST setting centers the IF in the IF bandwidth after each

measurement to improve tracking.
