Test Equipment Description


Manual operation using front panel or PC - control via optional IEEE-Interface.

Calibration Pulse Generators
are indispensable for the test of emi-receivers, especially the pulse weighting curves which are specified in the standards.

Calibration Pulse Generators up to now
For many decades the Schwarzbeck Calibration Pulse Generators IGLK 2914 (Band A, 9 kHz150 kHz and Band B, 150 kHz-30 MHz) and IGU 2912 (Band C/D, 30 MHz-1 GHz) have been recognised as world wide standard. Their mechanical relay contacts generate spectrum beyond 1 GHz with both high voltage and high precision.

And now the IGUU 2916

  1. The IGUU 2916 covers the complete frequency range from 9 kHz - 1 GHz. Obviously both relay contact generators with their 1-dB amplitude setting (main generators) are included with slight modification, because there is still no alternative.
  2. New Auxiliary Generators open the pulse frequency range beyond 200 Hz. So finally this limit of the mechanical relay contact has been overcome. Pulse frequency in the range of 0.1 Hz to 20 kHz is now available. This means complete testing of emi-receivers including detectors for cispr-quasi-peak, average and peak/mil.
  3. Rotary encoders and led-displays are used for pulse frequency and amplitude (main generator only) tuning and reading. Pulse frequency generation uses a crystal reference generator and dividers.
  4. The Sine Wave Generator provides the frequencies 100 kHz, 1 MHz, 10 MHz and 100 MHz with 60 dBmV. The generator uses output voltage control and is referenced to the crystal generator using frequency dividers and multipliers. This means sine wave/pulse comparison without an external signal generator.
  5. The optional Coaxial Switching Unit KU 9616 connects one of the four outputs of the IGUU 2916 to the e. u. t., controlled by the IGUU 291
  6. This is very convenient and time saving because there is no need to change coaxial connections. 6. The optional IEEE-Interface serves for complete PC-control of all generator functions. Automatic testing is possible by combining interface and coaxial switching unit.
