Base Frequency:  10MHz to 110GHz dependent on source, couplers and detectors.

The Agilent 8757A scalar network analyzer measures insertion loss, gain, return loss, SWR, and power quickly and accurately. With high-performance detectors and directional bridges, and a companion Agilent source and printer, this analyzer becomes the basis of a complete measurement system with superb performance. The Agilent 8757A features three detector inputs and two independent display channels, allowing simultaneous ratioed or non-ratioed measurement of your device's transmission and reflection characteristics.

Directional Bridge, 10 MHz to 18 GHz

Type-N (f) Agilent 85027 series directional bridges (AC/DC) The 85027 series directional bridges are designed to operate with either the 8757 in AC or DC detection modes or with the 8756 or 8755 in AC detection mode. This bridge offers high directivity, excellent test port match, and a measurement range of up to 18 GHz in coax.

The HP Model 11664A Detector must be used in conjunction with the HP Model 8757 Swept Amplitude Analyzer. The 11664A detects RF signal levels from -70 to +10 dBm in the frequency range from 10 MHz to 18 GHz. Use of three 11664A Detectors enables simultaneous (amplitude only) transmission and reflection measurement via the 8757 Analyzer/. The 11664A Detector and the input stages of the 8757 comprise an ac-coupled system. This detection scheme requires 27.8 kHz square wave modulation of the RF input signal provided from the HP 8757.
