Keysight 8720ES Vector Network Analyzer 50 MHz to 20 GHz 2 Port S-Parameter VNA

The Keysight 8720ES (originally introduced by Hewlett-Packard and later sold by Agilent Technologies) is a two-port microwave vector network analyzer covering 50 MHz to 20 GHz. It measures the transmission and reflection characteristics of RF and microwave components with high dynamic range and fast sweep, and remains a workhorse instrument for component production test and lab verification.

• Frequency range from 50 MHz to 20 GHz in a single two-port test set
• Wide dynamic range of 100 dB with 10 Hz IF bandwidth for high-rejection filters and duplexers
• Integrated S-parameter test set for S11, S21, S12 and S22 measurements
• Frequency resolution of 1 Hz for narrowband device characterization
• Selectable IF bandwidth from 10 Hz to 6 kHz for a speed-versus-noise trade-off
• Time domain option for distance-to-fault and cable and antenna analysis
• Colour display with multiple channels, traces and markers
• GPIB (IEEE-488) interface for automated production test

• Full two-port error correction with 12-term calibration for accurate S-parameter data
• Log magnitude, phase, group delay, SWR, Smith chart and polar display formats
• Limit lines, marker search and pass/fail testing for production screening
• Time domain transformation (with option 010) for fault location and gating
• Save and recall of instrument states, calibrations and trace data
• Automation via GPIB with standard SCPI command set

• Filter, duplexer, coupler and divider characterization up to 20 GHz
• Amplifier gain, return loss and group delay measurement
• Cable, connector and antenna return loss plus distance-to-fault testing
• Production test of microwave modules with automated limit testing
• Education and RF laboratory training on vector network analysis
