The 8645A agile signal generator is a 252 kHz to 2060 MHz synthesized generator that combines high performance with frequency agility. With this combination, test both stringent RF performance and fast hopping capability of frequency agile radios and surveillance receivers. In addition, the 8645A can simulate a complex environment to test for

The Keysight 8645A agile signal generator combines high performance with frequency agility for new fast-switching test requirements. These capabilities are important for performance testing of such devices as frequency agile radios and surveillance receivers.

The 8645A Agile Signal Generator provides specified signal performance in both static and agile operation. Fully-synthesized outputs with high timebase accuracy are standard when not frequency hopping. The Fast Hop mode activates a frequency-lock loop to allow frequency switching as fast as 15 uS from 120 MHz to 1030 MHz.

2013年7月29日 · In short :its a standard signal generator sporting AM FM pulse and phase modulation of a carrier between 260 Kilohertz and 1.03 GHz. The machine can sweep its carrier or 'hop' its carrier. In other words you can feed it a list ( up to 8000 ) preset frequencies and signal strengths and 'hop' from one preset to another.

The HP 8645A offers flexible and comprehensive control of the fre- quency hopping output. Parameters can be entered from the front panel, through the HP-IB port or using TTL inputs on the rear panel. Extensive hopped frequency simulations including hop frequencies, dwell times, hop rate, modulation, etc. can be entered into non-vola-

The 8645A is a 1 (or 2) GHz RF signal generator specifically designed to perform the most demanding tests on frequency agile radios and on state of the art communication systems; with its modulation, amplitude control, and sweep functions, the 8645A also performs in and out-of-channel tests on high-performance radios.

The HP Agilent 8645A, Signal Generator, that combines high performance 252 kHz to 1.030 GHz bandwidth, Frequency-Agile capability and frequency agility for new fast-switching test requirements.

The 8645A has been a real challenge. Not electronically, but with all the mechanical damage. Most of the defective parts are now fixed or replaced, the last one missing:

The 8645A agile signal generator combines high performance with frequency agility for new fast-switching test requirements. These capabilities are important for performance testing of such devices as frequency agile radios and surveillance receivers.
