Agilent Keysight 8722D 40GHz Microwave Vector Network Analyzer

Agilent Keysight 8722D Microwave Vector Network Analyzer

Features:

• 50 MHz to 13.5, 20, or 40 GHz frequency coverage
• New processor makes measurements and data transfers up to seven times faster
• Fast-sweeping, built-in synthesized source
• Integrated solid-state switching S-parameter test set
• Vecter receiver, error correcton, time domain
• Up to 105 dB dynamic range

Despite their affordable price, the HP 8720 series network analyzers offer remarkable performance. The integrated source is fully synthesized, even while sweeping, and provides stability and accuracy within 10 ppm (typical). Yet the sweep rate is extremely fast: measurement update times are typically about 1 ms per point. Frequency resolution is 1 Hz standard for accurate measurements of narrowband or long-delay devices.

The tuned receivers with variable bandwidth IF filters provide up to 105 dB of dynamic range. A built-in, solid-state switching test set measures both forward and reverse parameters with a single connection, and provides continuous updating of all four S-parameters as required for two-port error correction.

Two independent channels can simultaneously display two measurements, such as reflection and transmission responses. The receiver detects both magnitude and phase, and displays results in a variety of useful formats, including group delay, deviation from linear phase, complex impedance or admittance, and SWR on rectangular, polar or Smith charts.

Built-in vector accuracy enhancement provides excellent errorcorrected accuracy in all common coaxial connectors. A user kit supports user-defined standards, and allows calibration in waveguide (including effects of dispersion).

Specifications:

Option 012 provides direct sampler access, enabling the user to eliminate coupler loss and increase sensitivity by 16 dB. Option 012 allows filter rejection measurements to greater than –120 dB and allows insertion of attenuation between coupler and sampler. By using separate transmit and receive antennae, Option 012 can improve signal-to-noise in free-space measurements.

Option 085 is a high-power S-parameter test set modification allowing device test up to +43 dBm (20 watts) input and output. It deletes the bias tees, replaces the solid-state switch with a mechanical switch, and adds internal attenuators.
