This command specifies the frequency that the sweep function
starts with when SWE:DIR UP is enabled and ends with when
SWE:DIR DOWN is enabled.
[:SOURce]:SWEep:FREQuency:STOP
<value>
This command specifies the frequency that the sweep function
ends with when SWE:DIR UP is enabled and starts with when
SWE:DIR DOWN is enabled.
[:SOURce]:SWEep:FREQuency:MARKer
<value>
The 3152A’s sweep function can be synchronized with external
events using the marker facility. Choose a frequency between
the specified STARt and STOP as the location for the marker.
During each sweep cycle, the 3152A will output a marker pulse
in synchronization when the 3152A sweeps through the marker
frequency. The pulse will be available at the 3152A’s SYNC
OUT jack or output to a TTL trigger line as specified using the
OUTP:SYNC[:STATe] and OUTP:TTLTrg<N>[:STATe]
commands.
[:SOURce]:SWEep:FUNCtion < SIN | SQU | TRI >
This selects the shape of the waveform to be swept.
The sample clock frequency of the 3152A may be controlled
directly for the sweep function. Use the command:
[:SOURce]:SWEep:FREQuency:RASTer
<value>
to accomplish this.
Finally, use the command:
[:SOURce]:SWEep:TIME
<value>
to specify the duration of the sweep from start to end (or from
end to start if SWE:DIR DOWN is selected).
To terminate sweep mode, either reset the 3152A (*RST) or
select FUNC:MODE < FIX | USER | SEQ >.
