TCP305 and TCP312 Performance Verification
DC Gain Accura
cy
This procedure tests the DC gain accuracy of the TCP305 and TCP312 Current
Probes. In this test you compare the voltage output of the amplifier to a reference
input.
This test uses current loops that you make using wire and 3-inch forms.
Instructio
ns on making the current loops are available. (See page 4, Making DC
Current Loops.)
Equipment Connections
Using a BNC cable, connect the amplifier OUTPUT to the 50 Ω feedthrough
terminat
ion. Attach the termination to a BNC-to-dual banana adapter. Insert the
dual-banana adapter into the digital m ultimeter DC voltage input, taking care to
maintain polarity.
1. Connect the current loop to the current source as shown.
2. Connec
t the current probe to the PROBE INPUT connector. Do not connect
the probe to the current loop at this time.
