Depending on the
mode you have set, the corresponding
parameter is displayed.
"Step Lin"
The step width is a constant value in Hz.
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:STEP[:LINear]
"Step Log"
The step width is determined logarithmically in %, that means as a
constant fraction of the current frequency.
Successive frequencies are calculated as follows:
●
start_f < stop_f
f2 = f1 * (1 + step_log / 100)
If f2 > stop_f: f2 is set to stop_f.
●
start_f > stop_f
f2 = f1 / (1 + step_log / 100)
If f2 < stop_f: f2 is set to stop_f.
When the shape "Triangle" is set, the frequency values on the slope
from
stop_f back to start_f
are the same as on the slope from
start_f to stop_f
.
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:STEP:LOGarithmic
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 display update for optimum sweep performance
especially with short dwell times (see
Chapter 5.2.3.7, "Display Update"
Remote command:
[:SOURce<hw>]:SWEep[:FREQuency]:DWELl
Ext. Trigger Input Slope
Sets the polarity of the active slope of an externally applied instrument trigger.
This setting affects the TRIG input (BNC connector at the rear of the instrument).
"Positive"
activates the rising edge of the trigger signal.
