DC Gain Accuracy
Use the following procedure to verify the DC gain accuracy of the amplifier.
Refer to Figure 5--2 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 amplifier OUTPUT to the 50 Ω
precision 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 probe input to the current source:
a. Connect the BNC end of the Calibration 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 Calibration Adapter to the
amplifier at this time.
