Insertion Loss Measurement
This utility measures the loss associated with RF cables, filters, and other passive
devices in the measurement path. This test uses the Test Set internal source and
measures the relative loss through the cable or device. This utility sends no control
commands to the MSC.
To optimize measurement accuracy, the measurement setup uses two external 6-dB
attenuators (pads) and a short calibration cable. The pads are optional, but should be
used if available. These parts are not standard equipment with the Test Set, but are
included in the optional accessory kit (see “Optional Accessory Kits” on page 17).
