  • Page 15: Introduction

    Introduction Introduction The purpose of this manual is to help you use the 85110L S-parameter test set effectively and confidently. The 85110L is specially configured for operation in pulsed-RF measurement systems. Four 70-dB step attenuators protect each input of the fundamentally-mixed down-converter to allow measurement of test devices with output power of 50 watts CW.

  • Page 16: Compatibility

    “Contacting Agilent” on page iv). Characteristics The 85110L uses two synthesizers to act as the RF and LO sources for the four mixer based down-converter (Figure 1-1 on page 1-4). This approach eliminates the need to dedicate one channel for phase-lock, making full two-port, pulsed-RF S-parameter measurements possible.

Agilent offers several calibration kits suitable for calibrating an 8510C/85110L when making error corrected measurements.

  • Page 19: Precautions

    To protect the switch splitter, any power in excess of +17 dBm into a port of CAUTION the 85110L must be offset by an equal or greater amount of attenuation. The power into the test port must never exceed +47 dBm.
