Today there are many low-phase-noise applications for which a synthesizer is unsuitable and the HP8640 is still the generator of choice. The 8640 is configured as a 256 to 512MHz cavity oscillator followed by a bank of successive divide-by- two circuits.

The 8640 signal generator covers the frequency range 500 kHz to 512 MHz (450 kHz to 550 MHz with hand overrange) and can be extended to 1100 MHz with an internal doubler (option 002). An optional audio oscillator is also available to extend the CW output range of …

HEWLETT hp, PACKARD Signal Generator APPLICATION NOTE HP 8640A/B AN 170-1 OUTPUT LEVEL ACCURACY The HP 8640A and 8640B are signal generators which cover the frequency range of 450 kHz to

The HP 8640B is a signal generator with an output frequency range of 500KHz - 512MHz. Has digital display with 6-1/2 digits. FM modulation 400Hz and 1KHz. Output Level 1V rms 600 Ohm. AM 10mV to 0.5 to 512MHz modulation: 0 to 100%. Output Power switchable from …

Compare the absolute level accuracy of the 8640A/B AM/FM signal generator versus the earlier HP 608 series VHF signal generators. Output level control is accomplished by the modulator, the ALC loop, the output vernier and step attenuator. The modulator acts as a current- controlled attenuator which varies the RF output level.

2020年3月2日 · Errata Title & Document Type: 8640A Signal Generator Operating and Service Manual Manual Part Number: 08640-90114 Revision Date: October 1976 About this Manual We've added this manual to the Agilent website in an effort to help you support your product. This manual provides the best information we could find.

These generators provide AM, FM and pulse modulation. The 8640A has a mechanical, dial; the 8640B has a built-in counter and phase-lock synchronizer that locks the RF output frequency to the crystal time base used in the counter. Output level range of the 8640A/B is from +19 dBm to —145 dBm (2 V to 0.013 into 50 ohms).

This document summarizes the features and capabilities of the HP 8640A/B signal generators. It can generate signals from 450 kHz to 512 MHz with high spectral purity and stability. It provides fully calibrated AM, FM, and pulse modulation.
