Agilent/Keysight 85102R

The Agilent/Keysight 85102R is a test set component of the 8510 network analyzer system engineered for S-parameter characterization of microwave and RF devices. It delivers precise two-port measurements across extended frequency bands, supporting both reflection and transmission analysis with high dynamic range and calibrated accuracy.

– Technical Specifications

Frequency Range
Measurement capability extends from 45 MHz to 110 GHz depending on configuration. Typical configurations achieve measurements to 50 GHz; upper-band operation requires compatible millimeter-wave extensions.

S-Parameter Measurements
Full two-port S-parameter acquisition (S11, S21, S12, S22) with magnitude and phase. Reflection measurements include return loss, standing wave ratio (SWR), reflection coefficient, and impedance. Transmission measurements span insertion loss, transmission coefficient, gain/loss, group delay, deviation from linear phase, and electrical delay.

Dynamic Range and Power Performance
Receiver dynamic range reaches 106 dB; system dynamic range to 93 dB within specific frequency bands. Minimum detectable power at Port 2 extends to −97 dBm. Maximum power levels vary by frequency: +20 dBm at 0.045–2 GHz, decreasing at higher frequencies. Port 1 reference power nominally +2 dBm or −2 dBm.

Calibration
Supports full two-port calibration using standard kits (85052B for 3.5 mm; 85056A for 2.4 mm connectors).

– Key Features

• All four S-parameters with phase information
• Dynamic range to 106 dB receiver / 93 dB system
• Frequency coverage from 45 MHz to 110 GHz (configuration-dependent)
• Wide power measurement span (−97 dBm to +20 dBm)
• Two-port calibration support with standard kits

– Typical Applications

Characterization of passive and active RF/microwave components, filter and amplifier measurements, transmission line analysis, impedance profiling, and gain/loss determination across microwave bands.

– Compatibility & Integration

Designed for integration with the 8510 network analyzer mainframe. Control and data transfer via GPIB interface to compatible sources and analyzer systems.
