Picotest J2121A High Power Line Injector

Picotest J2121A



Picotest J2121A Features

  • 400V/20A max – Supports High Power 270V Military and Satellite Buss Applications
  • 100Hz – 1MHz bandwidth
  • Regulated Input-Output Voltage Drop, 500mV
  • Isolated Current Sense Monitor Output
  • Fan cooled, Includes low-noise power supply

Introduction

The J2121A is especially suited to high power applications such as those associated with military and satellite busses. It can be used with input bus voltages up to 400V and supply up to 20A at 1MHz. The line injector allows the input DC supply voltage to be modulated by the network analyzer source signal (oscillator). The J2121A line injector output is DC regulated and provides a fixed voltage drop of 750mV from the input bus voltage fed into the injector in addition to the AC modulation signal.
