REFRAD -- Reference Radiator, a comb generator that puts out pulses at 10 kHz or 1 MHz or 5 MHz spacing.
EMC Test Systems sells it under the model number REFRAD Model 4630B. The pulse amplitude is not specified, but the output is amplitude and frequency stable. Battery operated, can eliminate a lot of cable issues. > ---------- > From: Matejic, Mirko[SMTP:[email protected]] > Reply To: Matejic, Mirko > Sent: Wednesday, January 12, 2000 9:59 AM > To: [email protected] > Subject: RE: Chamber and OATS Coorelation > > > Barry, > Request was to measure radiated emission levels in compact semianechoic > room > and predict measured levels at a specific OATS.
