HP 3326A Two-Channel Synthesizer combines two independent synthesizers, flexible modulation, and control circuitry into a single, powerful package. This single instrument can provide precise phase offset, two-tone sweep, fast frequency switching, internal modulation, and pulse signals for bench or systems use.
Manual Internal Calibration results by Channel:
Channel A No Errors
Channel B Error 193 Fails DC Offset Calibration
Manual Multiphase Calibration results by Channel:
Channel A Error 191 Fails Phase Calibration
Channel B Error 191 Fails Phase Calibration
Monitoring the two channel outputs reveal Channel A amplitude is approximately twice that of the amplitude setting of 1V. Channel B is dead on.
