Remote command:
MEASure:MODE on page 207
Trigger source
Selects the signal source that initiates the measurement in manual mode.
Continuous
Starts the measurement and continues after a completed measure-
ment cycle automatically.
Manual
Starts the measurement on pressing the [Trig.] at the front panel.
After one measurement cycle, the measurement stops and waits for
the next manual trigger event.
Remote command:
*TRG on page 175
External
Starts the measurement initiated by an external trigger signal.
The falling edge of the signal triggers the measurement at the TTL
level of +5 V. Further signals received at the trigger input during a
measurement cycle take no effect until the current cycle is completed.
After one measurement cycle, the measurement stops and waits for
the next trigger signal.
To apply the external signal, connect the signal source to the Trigger
Input at the rear panel.
8.1.2 Working with the measurement modes
Using the continuous measurement mode
To measure a component sample in the default continuous measurement mode:
1. If the [Meas. Mode] key at the front panel lights up, press it to switch to continuous
mode.
The R&S LCX measures continuously with updates according to selected mea-
surement speed, see "Measurement Speed" on page 76.
2. Press the [Hold] key to keep the range setting constant.
The [Hold] key lights up. You can use the function, e.g. to measure a batch of the
same components.
3. To reactivate automatic range selection, press the [Hold] key again.
The key no longer lights up.
Using the manual trigger mode
This example describes the steps to be taken, for measuring a component sample at a
series of working points, triggered manually:
1. Press the [Meas. Mode] key at the front panel.
The key lights up. The R&S LCX stops a continuous measurement and waits for a
trigger event.
