Control Summary
For example, th
e typical accuracy of the TCP312A probe on the 1 A/V range is
1%. If you want to measure a 3 Ap-p, 1 kHz square wave and need increased
accuracy (better than 0.25% is attainable), first adjust the TCP312A on the 1 A/V
range setting using a calibrated 3 Ap-p, 1 kHz square wave source. Then, attach
the probe to your circuit and take your measurement. Remember, altering the DC
Gain Adjustment may cause the probe to not meet the warranted DC Accuracy
specificati
on.
GPIB Operation
The TCPA300 and TCPA400 Current Probe Amplifiers do not have direct GPIB
connections. However, you can use a computer to control the oscilloscope that the
amplifier
is connected to, enabling you to change the time and scale factors of
your current measurements over the oscilloscope GPIB bus.
Refer to
your oscilloscope manual for instructions on using the GPIB bus.
