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]


The PP-8444A/U is a state of the art high performance lightweight portable unit designed for field-deployment or use in a shop environment, to provide fast reactivation of various types of rechargeable batteries. The battery charger is housed in a non-conductive impact-resistant ABS molded equipment case. The case is completely watertight when the gasket on the cover is serviceable, securely latched and the pressure equalizer relief valve on the bottom of the case is closed. The Universal Battery Charger, has multi-voltage input for world wide usage. Figure 1 displays the Universal Battery Charger PP-8444A/U and NATO Cable Power Supply. Figure 2 (Sheet 1 and 2) and (Sheet 2 of 2) display the accessories.


The Fluke 77 satisfies the operational requirement to measure DC voltages in the range of 5mV to 1KV, with an accuracy of +/- (0.5% of reading + 1 count) with an input resistance of 10 megohms minimum; AC voltages in the range of 100mV to 750V with an accuracy of +/- (2% of reading + 5 counts), a frequency range from 45Hz to 1KHz (up to 320 volts) and 45Hz to 500Hz (up to 750 volts). the Multimeter is average responding and RMS indicating. It measures DC current in the range of 10mA to 10A with an accuracy of +/- (2% of reading + 3 counts); AC current in the range of 10mA to 10A with n accuracy of +/- (3% of reading + 2 counts) in a frequency range of 45Hz to 1KHz; resistance in the range of 0.1 ohms to 32 megohms with an ccuracy of +/- (2% of reading + 1 count). Overload protection is incorporated.


The Fluke 189M/AN Digital Handheld Multimeter (DMM) is a handheld multimeter capable of doing the following:

• 50,000 counts display
• 0.025% basic DC accuracy
• True RMS AC + DC measurements
• 100 kHz AC bandwidth for voltage and current
• Dual display with bargraph and two-level backlight
• Min/max/average with real time clock and 250 μs Fast Min-Max
• Frequency, capacitance, duty cycle & pulse width measurements
• Resistance, conductance, continuity and diode measurements
• Temperature and dBV/dBm with selectable reference
• PC interface for data exchange and closed case calibration
• Battery and fuse access without breaking calibration seal
• Internal memory allows stand-alone logging of up to 1000 measurements
• Readings memory for up to 100 readings


The TS-4348 Test Set was undertaken to provide the Marine Corps with a means to assess the performance quality of its night vision equipment at the user level. Before the introduction of the set, the Marine Corps had no way of establishing, prior to operational use, whether the image intensifier in a night vision device was operating within specification for gain and resolution. This set provides this capability.
