8920B Specifications Output Specifications describe the instrument’s warranted performance and are valid over the entire operating/ environmental range unless otherwise noted. RF IN/OUT Connector: Level Accuracy: ±1.2 dB (level ≥–127 dBm) If RF analyzer is also connected add ±0.1 dB Typically ±1.0 dB for all levels. Supplemental Characteristics are intended to provide additional information useful in applying the instrument by giving typical, but non-warranted, performance parameters.

Option 051, Rear Panel Connectors for TDMA Measurements for TDMA Option 800/801 This option provides the necessary rear panel connectors to work with the 83206A TDMA cellular adapter (8920B Option 800/801). Option 055, Mechanical Variable Input Attenuator This option replaces the standard electronic input attenuator with a mechanical version. Option 055 extends the RF source frequency range to 250 kHz to 1 GHz, and the RF analyzer measurement range to 400 kHz to 1 GHz.
