The HP 8757A features 76 dB of dynamic range (-60 dBm to +16 dBm) when used with the HP 11664 A/E detectors. With square wave modulation and detection (AC), the HP 11664 detectors enable reliable, drift-free measurements from 10 MHz to 40 GHz. With the HP 85025 and 8506 AC/DC detectors, make scalar measurements with or without modulation to 100 GHz. In DC mode (no modulation), use the HP 85025 A/B to make accurate swept-frequency measurements of power (dBm).
Options
001 - Adds fourth detector input
H02 - Deletes memory battery for save/recall registers enabling clear when power is turned off
H12 - Deletes memory battery and revises firmware for enhanced instrument security.
