A7597 – VIPER/T

VIPER/T is a portable, automated test unit that is operator-interfaced by a Laptop.  It is a modular design with 3 configurations: Radio Frequency (RF), Electro-Optical (EO), and a combined RF/EO.  The RF configuration will consist of the basic configuration plus additional test capability to screen RF Modules and Circuit Cards.  The EO configuration will consist of reduced capability RF-type configuration plus additional test capability to screen EO Modules and Circuit Assemblies.  The combined configuration has both RF and EO testing capabilities.  VIPER/T also has the capability of discrete component diagnostics.  Primary power input is 28VDC, provided via the standard NATO slave receptacle on a HMMWV and other vehicles.  Secondary input power is 108-220 VAC, 40-400 Hz.

VIPER/T currenlty has the following application program sets. (APS)

  • AN/PSM-117 (A7507)
  • [LAV]
  • [Saber - in planning]

A7705 – POWER SUPPLY – PP-8474

The general purpose rugged power supply converter provides the capability to convert 115 VAC to 24-28 VDC, 0-60 Amp for part number 713860-1 and 18-30 amperes for part number 715875-1. The power supply is environmentally rugged for use in the field to provide power to operate the equipment instead of using batteries.

This system replaced:

  • A12537G, PP-7333/GRC
  • E19067G, AN/USM-615 for use with the DSESTS power supply.

A7706 – POWER SUPPLY – XHR 40-25M

The XHR 40-25M, Power Supply will provides up to 40V and 25A of variable DC output for bench and automated test equipment (ATE) applications. It features universal input and power factor correction. Universal AC input lets you use line voltages around the world without resetting switches or adding on options. Power factor corrections gives you full output power from low voltage, low current AC outlets.

  • NEW version is WHITE with ID 10244B
  • OLD version is BLACK with ID 10244A

A7700 – CHRISTIE BATTERY CHARGER – PP/8333/U

The CASP/2000H(M) is a state of the art test instrument capable of performing all the functions needed by a typical battery user. It contains a microcomputer control system which will automatically process up to six batteries of most any type, and a programmable power supply based on the latest switch-mode technology. The compact front panel allows the user to easily initiate battery processing, monitor and evaluate ongoing functions, or to quickly set up for processing new batteries.

The CASP/2000H(M) performs the following functions:

  • Charge any rechargeable battery type.
  • Charge Nickel-Cadium batteries using the reFLEX charge mode.
  • Charge all batteries using an optimized charge mode.
  • Slow or “trickle” charge batteries.
  • Analyze batteries for discharge capacity.
  • Analyze batteries for charge capacity.
  • Recondition nickel cadium-batteries, eliminate memory.
  • Discharge nickel-cadium batteries for storage and shipment.
  • Provide power supply capability.

The only applicable use in the Marine Corps is to charge TOW Batteries... otherwise obsolete.

A7597 – TETS – AN/USM-657v3

TETS is a portable, automated test unit that is controlled by a Common Hardware Laptop computer. It is a modular design configuration using mature and proven Non-developmental Item components and modules to accommodate 3 configurations: Radio Frequency (RF), Electro-Optical (EO), and a combined RF/EO. The RF configuration will consist of the basic configuration plus additional test capability to screen RF Modules and Circuit Cards. The EO configuration will consist of the basic configuration plus additional test capability to screen EO Modules and Circuit Assemblies. The combined configuration will have both RF and EO testing capabilities. TETS will also have the capability of discrete component diagnostics. Primary power input is 28VDC, provided via the standard NATO slave receptacle on a HMMWV and other vehicles. Secondary input power is 108-220 VAC, 40-400 Hz.

TETS tested the following equipment (utilizing application program set (APS)):
MRC-142 (AN/PSM-107)
ULCS (AN/PSM-101)
TRC-170 (AN/PSM-105)
TPS-63 (AN/PSM-100)
TPS-59 (AN/PSM-106)
TAOM (AN/PSM-X10)
TPQ-46A (AN/PSM-109)
LAV (AN/PSM-97)
TOW (AN/PSM-111)
TAS-4C (AN/PSM-108)
TOW MGS/TU (AN/PSM-110)
AVENGER (AN/PSM-103)
EFV (AN/PSM-2XX)

A7501 (Huntron Tracker)

The Test Station, AN/USM-646 is a controlled diagnostic test instrument that utilizes Analog Signature Analysis (ASA) to isolate malfunctions in electronic modules. A sinewave stimulus is used to display the current versus voltage characteristic of an unpowered component on a CRT. The current/voltage characteristic is called an analog signature. The AN/USM-646 is software driven and is capable of storing the analog signature. This enables the technician to learn and save the signatures of a good module and utilize the stored signature to fault isolate defective modules.
