Section 2: Installation Model 2601B-PULSE System SourceMeter Instrument Reference Manual
2-10 2601B-PULSE-901-01A April 2020
Hazardous voltages may be present in the test system. To prevent injury or death, remove
power from the instrument or test system and discharge any energy storage components (for
example, capacitors or cables) before changing any connections that might allow contact
with an uninsulated conductor.
On some sensitive or easily damaged devices under test (DUTs), the instrument power-up and
power-down sequence can apply transient signals to the DUT that may affect or damage it. When
testing this type of DUT, do not make final connections to it until the instrument has completed its
power-up sequence and is in a known operating state. When testing this type of DUT, disconnect it
from the instrument before turning the instrument off.
To prevent any human contact with a live conductor, connections to the DUT must be fully insulated
and the final connections to the DUT must only use safety-rated safety-jack-socket connectors that
do not allow bodily contact.
4. To turn your instrument on, press the front-panel POWER switch to place it in the on (I) position.
5. To turn your instrument off, press the front-panel POWER switch to place it in the off (O) position.
Placing a 2601B-PULSE in standby
Placing the 2601B-PULSE in standby does not place the instrument in a safe state (an
interlock is provided for this function).
When the instrument is on, the output may be placed in an active output state (output on) or a
standby mode (output off). From the front panel, pressing the OUTPUT ON/OFF control toggles the
output using the present instrument configuration. You can also place the output in standby over the
remote interface by sending the following command:
smua.source.output = smua.OUTPUT_OFF
Even though the instrument is placed in standby, the output may not actually be off.
Warmup period
The 2601B-PULSE must be turned on and allowed to warm up for at least two hours to achieve
rated accuracies.
