CAUTION. Do not connect live circuits to the CABLE connector. Voltages
exceeding 5 volts can damage the pulser or sampler circuits.
Bleed the test cable of any residual static charge before attaching it to the
instrument. To bleed the cable, connect the standard 50 W terminator and standard
female-to-female BNC connector together, then temporarily attach both to the
cable. Remove the connectors before attaching the cable to the instrument.
When testing receiving antenna cables, avoid close proximity to transmitters.
Voltages may appear on the cable if a nearby transmitter is in use, resulting in
damage to the instrument. Before testing, be sure that there are no RF voltages
present, or disconnect the cable at both ends.
