Threat Simulator System Z2098B-185 Z2098B-186

System Description

Keysight's threat simulator is a fully integrated system. A single rack provides 2 channels (1 channel x 4 ports and 1 channel x 8 ports). Addition of a second identical rack expands the system to 4 channels (2 channels x 4 ports and 2 channels x 8 ports). All ports are aligned in amplitude, phase and time using the Z2098B-186 calibration system.

Simulation Capability (Z2098B-185)

The Keysight threat simulator provides complete measurement capability for:

  • Best in class RF Vector sources
  • Thermal stabilization to reduce phase and amplitude variation due to environmental changes
  • Each source is capable of simulating multiple emitters
  • Creation of overlapping pulses is supported using multiple channels

Calibration Methods (Z2098B-186)

The Keysight calibration system provides calibration and verification of the threat simulator by aligning amplitude, phase and time between the source rack and the System Under Test (SUT).

  • User guided calibrations for all measurement types
  • Non-intrusive in-situ phase and amplitude calibration and verification across multiple channels
  • Extremely fast amplitude/phase and time calibration
  • Verification software provided to validate calibration
  • Vector de-embedding to extend calibrations to your test interface
  • After calibration, data is uploaded to non-volatile correction tables in the sources.
  • In-situ calibration verifications for amplitude and phase whenever desired without disconnecting SUT
  • Only a single dimensional calibration is required to achieve the same results as the two-dimensional calibration on other systems
  • Acquisition of a full two dimensional calibration if desired

Mean Time To Repair (MTTR)

  • The use of Commercial Off The Shelf (COTS) equipment dramatically reduces the MTTR.
  • Typical MTTR for a single source failure is 30 minutes plus the time required to re-calibrate the system.

CalPod/Coupler Module In-Situ Calibration and Verification Concept

CalPods provide a way to quickly and easily refresh a network analyzer calibration, at the push of a button and without

removing the SUT or re-connecting standards. This capability is used to enhance the accuracy of the source calibration.

The VNA is used to monitor the coupled source signal close to the SUT. Using CalPods, the VNA calibration can be refreshed as needed prior to a source rack amplitude and phase calibration to provide the best possible performance. With the CalPods in place near the SUT inputs, the entire source calibration can be calibrated or verified while the SUT remains attached to the source. Support to initialize the CalPods and characterize the couplers is provided by the System Level Calibration (SLC) software included with the Z2098B-186 calibration rack.
