POWER ANALYST ® Wattmeter with Microprocessor Control and Digital Display

4391AThe ruggedly built, multifunction Model 4391A RF POWER ANALYST ® features a digital display, microprocessor based operation, and simplified, push button control.

This is a general-purpose wattmeter well suited to two-way communications, avionics and radar, telemetry, and standard radio and television applications.

  • Reads forward and reflected CW or FM power in watts or dBm.
  • Calculates SWR, return loss in dB and percent modulation.
  • Measures peak power for pulses as narrow as 0.8 µs.

Model 4380A-232 and 4380A-488 Interfaces for Remote Control of the Model 4391A

IEEE-488 & RS-232
Bus Interfaces
IEEE488

IEEE-488 or RS-232 interfaces let you remotely control the Model 4391A. The required 15-pin connector and internal cabling are installed in a new 4391A, or in older wattmeters having the suffix -832 in the model number (e.g. Model 4391-832).
Older units can be retrofitted at our plant.
