  • 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.
  • Model 4130B - Same as Model 4130 except uses 8 D cells instead of a 9V battery.
  • Model 4131 Tactical Radio Test Set. Tests 30 to 90 MHz FM transceivers. Includes frequency counter, wattmeter with load, and frequency modulated 0.5 uV RF output every 5 MHz from 30 MHz to 90 MHz. A 50 MHz FM demodulator is included, along with a relative field strength meter.
  • Model 4159 OEM thruline wattmeter. 225 to 400 MHz, 250 W.
  • Model 4198 OEM Thruline Directional RF Probe. 40 mW to 2 W. 4.4 to 5 GHz.
  • Model 4201 Series Multichannel RF Wattmeter. Input selector switches select one of 12 or 24 Thruline sensors to drive the forward and reflected meters.
  • Model 4301 Instructions Addendum
  • Model 4307 Thruline RF Wattmeter, 75 ohms, 2 MHz to 1 GHz, 25 W to 5 kW. the meter and sample can be separated by up to 3 feet for installed applications.
  • Model 4310 Peak Reading RF Wattmeter. 50 ohms, 50 W to 10 kW. 2 MHz to 1.26 GHz. An adjustable DC bias is applied in series with the diode detecting the RF. The resulting demodulated RF plus DC is observed on an oscilloscope. As the DC bias is adjusted, the lower power portion of the waveform on the scope disappears. The variable DC voltage drives the meter calibrated in watts. The power at any portion of the waveform can be determined.
  • Model 4311 - 4314 Thruline RF Wattmeter. 1 W to 10 kW average or peak. 450 kHz to 2.3 GHz.
