GENERAL INFORMATION
1-5
Option 005 - GMSK Bt 0.3
Provides GMSK Bt 0.3 modulation at a clock rate of 270.833 kHz in accordance with the
GSM and DCS 1800 specifications. The option includes a comprehensive internal data
generator.
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 009 - Pulse generator
Provides an internal generator with the ability to produce single and double pulses. Panel
connectors provide external trigger input and synchronisation and video outputs. Option 009
does not require the fitting of any other option, but it is designed to drive and be fully compatible
with Option 002 (Pulse Modulation).
Option 010 - DME modulator
DME (Distance Measuring Equipment) provides aircraft with accurate and continuous
information of slant range distance from a reference ground point. This option provides an
internal generator with the ability to produce gaussian shaped double pulses, and a linear RF
modulator which produces a similar gaussian shaped RF spectrum. Panel connectors provide an
external trigger input and synchronisation and video outputs. Option 010 requires Option 001
(Second Modulation Oscillator) and Option 006 (Avionics) to be fitted.
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.
