About this file
This single source justification document outlines the technical capabilities required of a Mark XIIB IFF test set. The test set must be capable of generating independent, realistic Mode 1, 2, 3/A, C, 4, S, and 5 interrogations and replies for testing Mark XIIB transponders and interrogators. It must support overlapping pulse groups of up to 32 pulses that accurately model constructive and destructive interference at RF. Up to 50 emitters are required with independent power settings and interrogation rates, plus the ability to control timing of all interrogations to create complex patterns. Replies from up to 25 emitters must support coherent Mode S ELS and EHS with real-time data and random RRD per reply. The related federal contract opportunity is solicitation number FA2823-23-Q-A046 from the Department of the Air Force Materiel Command Test Center to procure a VIASAT VRG-1000DC Mark XIIB IFF test set.

Single Source Justification (Simplified Acquisition)
UNCLASSIFIED
November 2018 UNCLASSIFIED Page 2 of 4
Realistic RF environment accounting for path loss and pointing angles Elementary surveillance (ELS) and enhanced surveillance (EHS) (optional) DIS (platform motion) interface (optional)
TRANSPONDER GENERATION
Modes Supported 1, 2, 3/A, C, 4, S, and 5 Frequency 1090 MHz Amplitude -90 to +6 dBm
TRANSPONDER RECEPTION
Modes Supported 1, 2, 3/A, C, 4, S, and 5 Frequency 1090 MHz Amplitude +15 to +65 dBm
Generates 50+ independent, realistic MarkXIIB Interrogations for testing MarkXIIB Transponders or Platforms containing MarkXIIB Transponders.
Generates 25 independent, realistic MarkXIIB Transponders for testing MarkXIIB Interrogators or Platforms containing MarkXIIB Interrogators.
Have two combined Input/output ports and four monitor ports.
Provide Sum and Difference channels to support mono-pulse tracking interrogator test.
Overlapping Pulse Groups
Up to 32 pulses that overlap in time will accurately garble at RF, producing mathematically correct constructive and destructive interference, without clipping.
Up to 32 interrogator or 25 transponder emitters can simultaneously generate interrogations or replies, respectively, all with independent parameters. Pulse groups can overlap in time at RF accurately as though they were generated from different sources.
Independent Interrogation Power Levels
Up to 50 emitters with independent power settings.
Up to 50 emitters with independent interrogation rates, with optional random start times to each emitter's signal pattern, plus optional jitter within each pattern.
Freedom to control timing of all interrogations to create arbitrary patterns of mixed interrogation modes and parameters. Requires multiple emitters on a single platform to generate complex interleaved interrogation patterns.
Replies
User can define sectors relative to the nose of the System Under Test to optionally suppress replies from certain angles.
Up to 25 emitters can be configured to generate coherent mode S ELS and EHS replies with real time data.
All emitters generating mode 5 replies independently pick a random RRD value per reply. Option to fix RRD per emitter.
