Setting Up and Making a Measurement
Making the Initial Signal Connection
Set the AM, FM, ΦM, or FM Stereo/RDS transmitter under test to transmit the RF
power. Connect the transmitting signal to the signal analyzer as below.
CAUTION
Before connecting a signal to the analyzer, make sure the analyzer can safely accept
the signal level provided. The signal level limits are marked next to the RF Input
connector on the front panel.
1. Connect the output AM, FM, ΦM, or FM Stereo/RDS transmitter to the RF input
2. (Optional) If there is a frequency reference port on the transmitter, connect it to

After making the connection, see the Input/Output key menu for details on
selecting input ports and the AMPTD Y Scale menu for details on setting internal
attenuation to prevent overloading the analyzer.
Using Analyzer Mode and Measurement Presets
To set your current measurement mode to a known factory default state, press Mode
Preset. This initializes the analyzer by returning the mode setup and all of the
measurement setups in the mode to the factory default parameters.
To preset the parameters that are specific to an active, selected measurement, press
Meas Setup, Meas Preset. This returns all the measurement setup parameters to the
factory defaults, but only for the currently selected measurement.
