Dwell Time - Frequency Sweep
Sets the dwell time. The dwell time determines the duration of the individual sweep steps.
The "Dwell Time" set by the user is used as the step time of the sweep. The effective net
dwell time is shorter, reduced by the setting time. This setting time may be greater than
the time specified in the data sheet.
Note:
It is recommended to switch off the GUI update for optimum sweep performance espe-
cially with short dwell times (see chapter 5.2.3.5, "Gui Update", on page 86).
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:DWELl on page 378
Use LF connector to output sweep voltage - RF Frequency Sweep
Activates the output of a linear voltage ramp from sweep start to sweep stop at the LF
connector. This signal can be used for the X-deflection of an oscilloscope. The voltage
range is determined below.
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:LFConnector on page 379
Output Voltage Start Freq - RF Frequency Sweep
Sets the voltage at the sweep start frequency.
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:OVOLtage:STARt on page 380
Output Voltage Stop - RF Frequency Sweep
Sets the voltage at the sweep stop frequency..
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:OVOLtage:STOP on page 381
Trigger Input Slope
Sets the polarity of the active slope of an applied instrument trigger.
This setting affects the INST TRIG input (BNC connector at the rear of the instrument).
"Positive"
The rising edge of the trigger signal is active.
