  • Model 3126, 3127, 3128 Wattcher RF Monitor/Alarm.
  • Model 3142 Power Reduction Test Set. 1 kW PEP, 250 W average. Includes RF wattmeter (50 W and 1 kW full scale) and attenuated output ( 0 to 15 dB).
  • Model AT-100 Antenna Tester. Measures VSWR, Return Loss, Rho, and relative field strength 2 to 136 MHz.
  • Model 3170, 3171, 3172, 3173 Thruline High Soeed Wattcher. 100 mW to 250 kW.
  • Model 3180 FM Deviation Indicator. Thruline coupler with 50 MHz FM receiver.
  • Model 3316A Filter Coupler to measure peak output power of TACAN transmitters.
  • Model 3900 Frequency Counter / Wattmeter
  • Model 4029 Power Sensor Calibrator. Used to set calibration factors for different frequencies in the 4020 series power sensors.
  • Model 4030 Relative Field Strength Element. Plugs into model 43, 4430, or 4431 wattmeter and drives the wattmeter's meter with a current proportional to the received RF field. The element has a small antenna and is sensitive to 1 MHz to 1 GHz. 1 watt at 150 MHz 8 feet away will cause full scale deflection.
  • Model 4110 Series RF Test Set. A meter and thruline screwed together. By choosing elements, measurements from 2 to 76 MHz and 5 to 100 watts can be made.
  • Model 4111 Series Thruline Wattmeters. Models 4111, 4112, 4113, 4114, 4115, 4116, 4118, and 4120 cover 50 watts to 1.26 kW over various ranges between 2 to 512 MHz.
  • Model 4127 RF Test Set for AN/PRC-70 radio. Thruline meter with termination. 2 to 76 MHz. 5 watts to 40 watts full scale. Termination rated at 15 watts continuous or 40 watts intermittent (2 minutes on, 10 minutes off).
  • Model 4130 Tactical Radio Test Set. Includes a thruline wattmeter from 0.5 to 100 watts between 30 and 90 MHz. Also includes an RF generator that is frequency modulated. The outputs are every 5 MHz from 30 MHz to 90 MHz and at a level of 0.45 uV. Finally, the 4130 can measure relative field strength.
