The Keysight 8643A signal generator has been optimized to provide the performance required for out-of-channel receiver tests while maintaining a low price. Many performance capabilities have been included as standard, such as pulse modulation. Reliability is enhanced by an electronic attenuator on the 1 GHz version.

2022年1月7日 · The HP 8643A 1 GHz/2 GHz and HP 8644B 1 GHz/2 GHz RF signal generators are replacements for the HP 8644A.

he electronic attenuator used in the 8643A provides increased reliability. Instead of using mechanical relays, the electronic attenuator uses so. id-state components for setting output levels accurate to within ±1.0 dB. The Agilent patented design uses …

Part Number: 08645-90145 (Jan98). This service manual is provided for information only. The 864x and 866x products are no longer sold by Keysight. Yes, I would like to receive …

Instead of mechanical relays, the 8643A uses solid state components accurate to within 1.0 dB for setting levels. An advanced internal modulation synthesizer provides coverage to 400 kHz and two-tone capability with the selection of sine, square, triangle, sawtooth, and white Gaussian noise waveforms.
