HP8640B Signal Generator
The Hewlett-Packard 8640B is an RF signal generator. It supplies signals from 500kHz to 512MHz. With a frequency doubler, the frequency range can be extended to 1024MHz. However, as the frequency ranges overlap, the adjustable frequency range is 450kHz to 550MHz (or 1100MHz with an external doubler).
Eigenschaften:
- Frequency range: 450kHz - 550MHz (1100MHz with doubler)
- 10 frequency bands. Adjustable in steps of one octave (0.5MHz - 1MHz, 1MHz - 2MHz, 2MHz - 4MHz, 4MHz - 8MHz, 8MHz - 16MHz and so on...)
- FM and AM modulation; both external and internal via the 440Hz/1000Hz oscillator
- Output power: +20dBm to -145dBm adjustable in 10dBm steps on the attenuator and fine adjustment via potentiometer
- Frequency counter: 6 digits. Depending on the frequency range, an accuracy of 0.1Hz to 10kHz. Measurement of external signals is also possible
- Input for external 5MHz reference frequency and output for the internal reference
