GENERAL INFORMATION
1-7
Options
The following factory-fitted options are available:
Option 001 - Second modulation oscillator
An additional modulation oscillator is available to enable greater flexibility. This second oscillator
has the same specification as the first and allows full use of complex modulation modes.
Option 002 - Pulse modulation
The pulse modulation facility allows radar RF and IF stages to be tested and features rise and fall
times of less than 25 ns with an on/off ratio of better than 70 dB.
Option 006 - Avionics
Provides internally generated modulation waveforms suitable for the testing of Instrument Landing
Systems (ILS) and VHF Omni Range (VOR) beacons.
Option 008 - RF profiles and complex sweep
The RF profile facility provides compensation for frequency dependent level errors introduced by
cables, amplifiers and signal combiners. The complex sweep facility generates sweeps whose step
size, step time and RF level change while the sweep is in progress. These features are particularly
useful for EMC, Tempest and ATE applications.
Option 012 - Electronic attenuator
Designed to meet demanding extended life requirements for repetitive switching, such as are
found in high volume production applications.
Option 100 - Single fuse
A single fuse is used in place of the standard double fuse.
Option 105 - Modified pulse modulator
Modifies the pulse modulator (Option 002) to provide a slower rise and fall time for testing time
domain duplex and time domain multiple access receivers.
Option 112 - EXT MOD 2 input 600
Ω
The EXT MOD 2 INPUT socket has a 600
Ω
input impedance in place of 100 k
Ω.
