In summary, the Agilent (HP) 8564EC is a portable swept-tuned RF/microwave spectrum analyzer covering 9 kHz (30 Hz with Option 006) to 40 GHz with internal mixing, and up to 325 GHz with external waveguide mixers. The 8564EC provides resolution bandwidths from 1 Hz to 2 MHz, displayed average noise level performance suitable for low-level signal work, and a complete suite of trigger, sweep, and time-gated measurement modes.
The 8564EC is used for RF and microwave signal observation in the frequency domain — identifying signals, measuring their power, characterizing harmonics and spurious emissions, performing EMC pre-compliance measurements, monitoring transmitter output, and hunting interference. With the appropriate option, the 8564EC also performs time-gated spectrum analysis for burst signals and TDMA waveforms.
The 8560 E-Series predates the current X-Series (Keysight N9000 family). The architecture is swept-tuned rather than FFT-based, which means the 8564EC is at its best with narrowband signals, harmonic searches, and CW measurements rather than wide-instantaneous-bandwidth modulated-signal analysis. For traditional swept spectrum measurements, the 8564EC remains a fully capable, well-supported, well-documented instrument with a deep installed base and extensive aftermarket support.
Frequency reference accuracy with the standard timebase is ±1 × 10−7/year aging plus ±1 × 10−8 temperature stability over −10 to +55 °C. With Option 103 the aging tightens to ±1 × 10−7/year and initial achievable accuracy to ±2.2 × 10−8. Noise sidebands at 1 GHz center, 10 kHz offset are ≤ −113 dBc/Hz. Marker counter accuracy at 1 GHz with 1 Hz resolution is ±225 Hz after 5-minute warm-up.
The 8560 family was Hewlett-Packard's (later Agilent's) flagship portable spectrum analyzer line in the late 1990s and 2000s. Even today, the family remains heavily represented in defense, aerospace, calibration laboratory, and university research environments where existing test procedures, fixtures, and remote-control programs are written specifically around 8560-series command sets. The product is fully compatible with HP/Agilent 33330D/E external detectors, 85370 series external mixers (up to 325 GHz), and standard IEEE-488 automation.
The 8564EC is supplied with the standard accessory complement for the instrument. Optional external waveguide mixers (for coverage above 18 GHz internal limit), tracking generators, frequency reference cables, and rack-mount kits are configured on a per-order basis. Contact your Test Architect to confirm the connector type, option set, and any required adapters for your test setup.
