2-10 Remote Operation Series 2600 System SourceMeters User’s Manual
2600S-900-01 Rev. A / May 2006 Return to In this Section:
The procedure assumes the DUT (10k
Ω
resistor) is already connected to the
SourceMeter ( Figure 1-3 in Section 1 of this manual), and that the instrument
resource has already been opened (“ Open and close an instrument resource ”
earlier in this section).
WARNING 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 2600
while the output is on. Power off the equipment from the front
panel or disconnect the main power cord from the rear of the
SourceMeter 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.
Step 1: Reset instrument
A good practice is to reset the instrument to its default settings before the start of
a test. To reset the SourceMeter, type the following command into the console
window, then press the
Return key:
reset()
For Model 2602 or 2612, you can restore defaults of Channel A or Channel B
respectively as follows:
smua.reset()
smub.reset()
Step 2: Select source function and set output value
Enter the following commands to select the source voltage function, set the
source range to 20V (Models 2611/2612) or 40V Models 2601/2602), and set the
source value to 10V:
smua.source.func = smua.OUTPUT_DCVOLTS
smua.source.rangev = 40
(use for Models 2601/2602)
smua.source.rangev = 20
(use for Models 2611/2612)
smua.source.levelv = 10
Step 3: Set compliance value and measure range
Enter the following commands to set the compliance limit and measure range to
10mA:
smua.source.limiti = 10e-3
smua.measure.rangei = 10e-3
