The 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. The HP 3326A can provide two signals whose phase is adjustable and calibrated anywhere in its 13 MHz frequency range without an external phase meter . Self-calibration can be performed internally or externally and yields accuracy of ±0.2 degrees below 100 kHz. Phase can be set with 0.01 degree resolution at all frequencies. Using its unique phase-calibration circuitry, calibrated multi-phase signals are easily achieved with two or more HP 3326As. Specifications. Operating Modes; Two Channel: Channels A and B are independent. Two-Phase: Channels A and B are the same frequency, with calibrated phase offset between the two signals. Two-Tone: Channel B frequency offset 0 to 100 kHz from channel A frequency. Pulse: Channel B is the complement of Channel A. Frequency (Waveforms are Sine, Square, Pulse, and DC); Range: 0 Hz to 13 MHz. Resolution: 1 µHz below 100 kHz, 1 mHz at and above 100 kHz. Stability: ±5 x I0^- 6/ year, 20°C to 30°C. Output Connectors: Front panel BNC female. Impedance: 50 ohm; output may be floated to ±42 V peak. Option 001, High Stability Frequency Reference. Option 002, High Voltage Output. Option 003, Rear Terminal Outputs.
