N9917A-210 - Keysight Technologies Inc. Vector network analyzer..

• Vector network analyzer
• Transmission/reflection (S21, S11), magnitude and phase
• 30 kHz to 18 GHz
• Directivity > 42 dB, dynamic range 100 dB to 9 GHz, 90 dB to 18 GHz
• Flat output power ( 1 dB) across whole frequency range, adjustable in 1 dB steps

A base N9917A combination analyzer includes a cable and antenna analyzer. Option 210 adds:

• A vector network analyzer mode with transmission/reflection or S21 and S11 measurements, both magnitude and phase. Available calibrations are CalReady, one-port OSL, response and enhanced response.
• Insertion loss measurement to the base cable and antenna analyzer or CAT mode.
• 2-port transmission measurement to the vector voltmeter mode, available as Option 308.
• Tracking capability to the spectrum analyzer independent source, available as Option 233 (source and spectrum analyzer set to sweep a frequency range, in sync)

This option can be added as a product upgrade.
