Test Equipment Setup
4
Use the following procedure to verify the DC gain accuracy of the amplifier.
Refer to Figure 1 and set up the test equipment as follows:
1. Connect the output of the amplifier to the DMM.
a. Connect a BNC Cable from the AM 503B/AM 5030 OUTPUT to the
50 feedthrough termination.
b. Attach the termination to a BNC-to-dual banana adapter.
c. Observe polarity and insert the dual banana adapter into the digital
multimeter DC voltage input.
2. Connect the input to current source.
a. Connect the other BNC cable from the Voltage Adapter to a BNC-to-
dual banana adapter.
b. Observe polarity and insert the dual banana adapter into the current
source DC output. Do not connect the voltage adapter to the amplifier at
this time.
