The HP E8663B Analog Signal Generator is a fully synthesized signal generator with low phase noise and high output power.
Specifications apply over a 0 to 55°C range, unless otherwise stated, and
apply after a 45 minute warm-up time. Supplemental characteristics,
denoted as typical, nominal, or measured, provide additional (non-warranted)
information at 25°C, which may be useful in the application of the product.
The E8663B Option HAR is a frequency divider designed to provide improved
phase noise in the 0.98 MHz to 500 MHz frequency range of the E8663B Signal
Generator.
The Option HAR uses frequency division as a replacement for heterodyne mixing
to create frequencies in the 0.98 to 500 MHZ range. This provides improved phase
noise in this mode. The mode will be referred to as "Divider Mode."
The HP E8663B Analog Signal Generator may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
Fully synthesized analog signal generator designed to produce low phase noise continuous wave signals from 100 kHz to 3.2 GHz (or optionally up to 9 GHz) with 1 mHz frequency resolution and output power ranging from typically -135 dBm to +18 dBm (or up to +21 dBm). It supports AM, FM, and phase modulation with fast step and sweep capabilities, enabling precise frequency and amplitude control for RF test, calibration, and development applications requiring clean and stable signals with minimal close-to-carrier phase noise.
Platforms
Designed for operation within RF and microwave test systems, this analog signal generator integrates with network analyzers, spectrum analyzers, and modulation analyzers via standard RF connectors and GPIB/LAN interfaces. It is utilized in benchtop and automated test environments across communications, radar, and electronic warfare platforms, providing stable carrier signals with low phase noise for component testing, system verification, and calibration of receivers and transceivers.
Applications
The equipment generates continuous wave and modulated RF signals from 100 kHz to 3.2 GHz with phase noise performance of -143 dBc/Hz at 20 kHz offset (1 GHz carrier). Applications include receiver sensitivity testing, local oscillator substitution, blocking and selectivity measurements, amplifier characterization, and component testing. Used extensively in wireless communications testing for GSM, CDMA, W-CDMA standards, aerospace/defense radar system development, and manufacturing test of RF modules. Provides stimulus signals for network analyzer measurements, EMC pre-compliance testing, and research laboratories requiring stable, low-noise RF sources for experimental setups and prototype validation.
Interfaces
2x USB, IEEE-488 (GPIB), RS-232, 10 MHz reference input/output, BNC connectors for analog signal outputs.
Specifications
Radio frequency signal generator operating from 100 kHz to 9 GHz with amplitude range of -137 to +13 dBm. Features precision frequency synthesis with 0.1 Hz resolution, low phase noise performance, and amplitude accuracy of ±1 dB. Provides AM, FM, and phase modulation capabilities with internal and external modulation sources. Equipped with standard 50-ohm RF output connector, GPIB and RS-232 interfaces for remote control, and front panel keypad with LCD display for local operation. Used for testing RF receivers, transmitters, amplifiers, and communication systems requiring stable test signals across VHF, UHF, and microwave frequency bands.
