IGUU 2918, Calibration-Pulse Generator for CISPR 16 Receivers

The enhanced auxiliary generators have an extended pulse frequency range from 0.1Hz to 1MHz (Band C/D). Now it is possible to test all previous detectors and additionally also True RMS detectors.
Rotary encoders and matrix - displays are used for pulse frequency and amplitude (main generator only) tuning and reading. The new keypad allows a direct entry of the desired frequency and amplitude. Pulse frequency is derived from a DDS-IC.
The optional Coaxial Switching Unit KU 9618 connects one of the four outputs of the IGUU 2918 to the e. u. t., controlled by the IGUU 2918. This is very convenient and time-saving because there is no need to change coaxial connections.
The GPIB - Interface serves for complete PC-control of all generator functions. Automatic testing is possible by using the interface and coaxial switching unit KU 9618.
