"Edge ..." Measured value triggering due to a voltage edge detected at the ana-
lyzer input on the trigger channel; can only be selected in the multi-
channel analyzers if the trigger channel is switched on.
This start condition can be combined with any sweep and has no
effect on the sweep x-axis.
Level monitoring is started by sweep stepping or - if the sweep sys-
tem is inactive - by pressing [START ] or [SINGLE ]. However, it is not
put on alert until a level beyond the start level (outside of the start-
stop interval) is measured. Triggering occurs at the moment when the
level first enters the range between start and stop (edge triggering).
When this occurs a single measurement is started, if necessary after
a specified delay.
In the case of continuous measurement, a further triggering in the
specified range occurs only if in the interim the level has left the set
range and moved in the direction of the start level. This means that
level monitoring is not put on alert again until a level beyond the start
level is detected.

Delay
Delay for Start Cond.
You can enter a delay for the "Start Cond Auto" menu item.
It applies under the following conditions:
●
Signal change on the generator (value entry, value change via rotary knob)
Signal change on the generator by entering a value
●
Performance of sweeps
●
[Stop/Cont ] or [Start ] (Continuous Measurement)
●
[Single ] (Single Measurement)
●
Change in the Analyzer panels
●
Change in the Generator panels
●
Change in the Filter panel
The "Delay" setting determines the time that must elapse between the above events
and restarting of the measurement so that, for example, a DUT has sufficient time to
settle. The total measuring time – i.e. the time that elapses until the measuring result is
available – is thus increased by the specified delay.
Note: In the case of continuous measurement, a delay is only applied to the first mea-
surement after the [Start]. No delay is applied to subsequent measurements.
Note: If the overall delay (including internal delays) is greater than 2 s, the measure-
ment will not be restarted automatically if changes are made at the generator, analyzer,
or filter bank.
Note: The delay is applied to all measured channels. In the case of multichannel ana-
lyzers, the delay only extends the total measuring time of the first partial measurement
(first pair of channels); all further (measured offline) channel pairs can be measured
without an additional time loss.
