DE MOD CHAN i-selects a demodulation measurement on Channel 1 and displays
the demod types menu.
DEMOD CHAN 2-selects a demodulation measurement on Channel 2 and displays
the demod types menu.
DEMOD ON OFF-activates demodulation and displays the DEMOD SELECT soft­
key. Chapter 5 has instructions for using demodulation. This softkey
appears only when LINEAR RES is active.
DE MOD SELECT-displays the demodulation softkey menu, which is used to select
the type of modulation, the channels, the carrier frequency and the remove
frequencies. This softkey appears only when DEMOD ON OFF is ON.
EDIT LlNE#-used to specify the edit line in the delete frequency table. Press EDIT
L1NE#, then enter the line number using the Entry group. The edit line is
highlighted in the table.
FM CHAN i-selects FM demodulation for Channel 1.
FM CHAN 2-selects FM demodulation for Channel 2.
LINEAR RES-configures the instrument to the linear resolution mode. Linear resolu­
tion provides fast Fourier transform (FFD measurements from 0 to 100 kHz.
The time throughput and demodulation features can also be used with the
linear mode. This mode offers the greatest number of measurements, dis­
plays and averaging features in the instrument.
LINEAR SWEEP-selects linear frequency sweeps in the swept sine mode. This
selection must be made prior to starting the sweep.
LOG RES-configures the instrument to the log resolution mode. This mode offers
fast Fourier transform (FFD measurements with a logarithmic frequency
axis. The frequency response and power spectrum measurements are
available in log resolution.
LOG SWEEP-selects logarithmic frequency sweeps in the swept sine mode. This
selection must be made prior to starting the sweep.
PM CHAN i-selects PM demodulation for Channel 1.
PM CHAN 2-selects PM demodulation for Channel 2.
