COUNT:
Sets the trigger count (number of measurements) as follows:
•
FINITE
: The instrument goes through measurement cycles for the programmed trigger count (1 to
99999).
•
INFINITE
: The instrument goes through measurement cycles indefinitely until halted.
INTERVAL:
Sets the time interval between measurements (0 s to 999.999 s) when the count is
greater than 1.
DELAY:
Sets the delay period between the trigger and the start of measurement (0 s to 999.999 s).
Front-panel triggering example
This example configures the trigger parameters to meet the following requirements:
•
Manual triggering (TRIG key)
•
Infinite trigger count (cycle indefinitely through measurement cycles)
•
Interval (time between measurements): 1 s
•
Delay (time from trigger to measurement): 2 s
To configure the trigger parameters:
1. Press
the
CONFIG
key, and then the
TRIG
key.
2. Select
TRIGGER-IN
, and then press the
ENTER
key or the navigation wheel

7. Press
EXIT (LOCAL)
to return to the main display.
8. Press
the
OUTPUT ON/OFF
control to turn the output on.
9. Press
TRIG
. A 2 s delay occurs before the first measurement. The instrument cycles through
measurements indefinitely with a 1 s interval between measurements.
10. Press the
OUTPUT ON/OFF
control again to stop taking readings.
Configuring for measure-only tests using the MODE key
In addition to being used for conventional source-measure operations, the Model 2657A can also be
used like a meter to measure current, voltage, resistance, or power.
To configure the Model 2657A as a V-meter, I-meter, ohm-meter, or watt-meter:
1. Press
the
MODE
key.
2. Turn the navigation wheel
to select the type of meter from the menu (
I-METER
,
V-METER
,
OHM-METER
, or
WATT-METER
).
3. Press
the
ENTER
key to complete the configuration of the Model 2657A as the selected meter.
