ET91 2.4 MHz Level Test Meter


FOUR INSTRUMENTS IN ONE

  • Level Meter, for selective and wideband level measurements with auto ranging
  • Generator, for the generation of measuring voltage for the test of FDM systems
  • Bridge, for the measurement of input and output parameter
  • Spectrum Analyser, for the test of output PSD, cross-talk and other interference signals

LEVEL METER

  • Comfortable receiver frequency setting modes like: CARRIER+TONE or CARRIER-TONE

  • Selective level measurement of multi tone test signal (MTTS)

GENERATOR

  • Generation of quartz accurate test signal with a resolution of 1 Hz
  • Generation of multi tone test signal (MTTS)
  • Generation of test signal in sweep mode

BRIDGE

  • LCL balance versus frequency
