Series 2600B System SourceMeter® Instrument Reference Manual
Hazardous voltages may be present on the output and guard terminals. To prevent
electrical shock that could cause injury or death, never make or break connections to the
Series 2600B while the output is on. Power off the equipment from the front panel or
disconnect the main power cord from the rear of the Series 2600B before handling cables
connected to the outputs. Putting the equipment into standby does not guarantee the
outputs are not powered if a hardware or software fault occurs.
To perform power measurements from the front panel:
This procedure requires dual-channel instruments (Models 2602B, 2604B, 2612B, 2614B, 2634B,
and 2636B) to be placed in single-channel display mode. For these models, press the DISPLAY key
to select single-channel display mode. See
1. Set source function and value. Press the SRC key to select the voltage or current source function
as required.
2. Set the output voltage or current to an appropriate value. See Step 1 of
measure procedure
3. Press the LIMIT key and set the voltage or current limit high enough for the expected voltage or
current across the DUT to be measured. See Step 2 of
(on page 2-32) earlier in this section.
4. Press the MEAS key as many times as needed to display power.
5. Press the OUTPUT ON/OFF control to turn the output on.
6. View the displayed reading (press the TRIG key if necessary).
7. When finished, press the OUTPUT ON/OFF control again to turn the output off.
Power measurements using the remote interface
The following paragraphs summarize basic power measurement commands using the remote
interface and also give a programming example for a typical power measurement situation.
Remote power reading command
The programming example below illustrates how to obtain a power reading from SMU A:
reading = smua.measure.p()
See Remote source-measure commands
source and measure functions and also
Power measurement programming example
The following programming example illustrates the setup and command sequence for a typical power
measurement procedure with the following parameters:
•
Source function: voltage, source autorange, 5 V output
•
Current measure function and range: current, autorange
•
Current compliance: 50 mA
