Preliminary Setup
Connecting the HP 4934A to the Test Circuit
CAUTION Ensure no more than 200 V dc or 10 V rms at 60 Hz is connected between tip and
ring of the TRMT or RCV jacks.
1 The two 310-type jacks of the HP 4934A can function as a Transmitter output or
Receiver input. Pressing the REVERSE key causes the function of the two 310-
type jacks to be reversed. The current function of the ports is indicated by the
indicators below the REVERSE key.
2 If the line to be tested is already terminated, press BRDG.
3 Select
the
receiver
input impedance using the
RCV key - 135,150,600, 900
or
12000. When operating in BRDG (bridged) mode, still ensure the correct
impedance is selected.
