Figure 4-8. Diode Testing Connections
Function modifiers:
None
Four soft keys allow changing the test voltage and current applied to the diode through
the test leads. The compliance voltage is set to either 5 volts or 10 volts. The compliance
current is set to either 1 mA or 0.1 mA. Press the appropriate soft key to select the desired
voltage and current setting.
Making a Triggered Measurement
Triggering the Meter’s measurement cycle is set through the trigger menu and performed
via a connection on the Meter’s rear panel or the front panel trigger key. The trigger
menu also allows setting a trigger delay and setting the number of samples or
measurement cycles taken for each trigger received. All trigger function parameters are
accessed through the measurement setup key.
Press Lto see the measurement setup menu.
A measurement trigger can also be initiated through the IEEE 488 port with a remote
command. This method of triggering is covered in the DMM4040/4050 Programmers
Manual.
Setting the Trigger Mode
The Meter’s measurement cycle can be initiated either by the internal measurement
circuit or by external stimulus.
To select the trigger mode:
1. With the measurement setup menu displayed, press the soft key labeled TRIGGER.
If EXT TRIG is highlighted, the Meter’s measurement cycle is triggered externally
either through the external trigger jack on the rear panel, or the trigger key on the
front panel. If EXT TRIG is not highlighted, then the Meter’s measurement cycle is
triggered automatically by its internal circuitry.
2. Press the soft key labeled EXT TRIG to toggle between internal and external
triggering.
