Features and Functions
Ext - (Ext requires LAN option on 34460A) the instrument issues one trigger each time an edge of the
appropriate slope arrives at the rear-panel Ext Trig connector. You can specify the slope on the softkey
menu that appears when Trg Src is set to Ext.
Level - (34465A/70A with DIG option only) the instrument issues one trigger when the specified meas-
urement threshold with the specified positive or negative slope occurs.
In the Single, Ext, and Level modes, you can specify the number of samples to be taken per trigger by
using the Samples/Trigger softkey. The Single and Ext modes can both buffer up to one trigger, meaning
that if you press [Single] or receive an external trigger while a series of measurements is in progress, the
instrument will finish that series of measurements and then immediately launch a new series of meas-
urements based on the trigger.
If multiple [Single] or external triggers are issued during a series of measurements, all triggers received
after the first are discarded.
The [Acquire] menu also configures the delay that occurs before each measurement is taken, regardless
of the trigger mode (Auto, Single, or Ext). This may be either automatic (the delay is based on the DMM's
settling time) or manual (you specify the delay time).
Finally, note the [Run/Stop] and [Single] keys on the front panel. In Auto trigger mode, pressing [Run-
/Stop] stops and resumes measurements, and pressing [Single] switches the instrument to single trigger
mode. In the Single and Ext modes, pressing [Run/Stop] stops readings if they are in progress, or switches
the mode to Auto if readings are stopped.
