PNA and ENA Network Analyzers Frequency Converter and Mixer Test Selection Guide
Keysight Technologies, Inc. offers a variety of network analyzers with the frequency, performance, and versatility to meet your measurement needs. This selection guide is designed to aid in selecting the required instruments and options to perform calibrated frequency-offset measurements using the PNA and ENA network analyzers.
The PNA and ENA frequency-offset mode options allow the source stimulus and the response receivers to be independently tuned to different frequencies which enable measurements on frequency-translating devices.
●Built-in second source:
For PNA-X (2- and 4-port) and 4-port PNA-L models, a built-in second source is available to simplify mixer measurement setups eliminating the need for an external LO source, and allowing for LO match, fixed and swept-LO testing. Plus, the internal second source improves sweep speed by at least 20 times compared to using an external source.
●Advanced calibrations:
The PNA and ENA implement two unique calibration techniques. The scalar-mixer calibration (SMC) is used for high-accuracy, magnitude-only conversion gain/loss measurements and requires a compatible power meter and power sensor. The vector-mixer calibration (VMC) is used for both magnitude and phase conversion gain/loss measurements.
Vector-mixer calibration is optimized for system calibration when phase and absolute group delay measurements are desired. This technique requires a reciprocal calibration mixer. This mixer is specific to each test configuration and must be acquired separately. In addition, the PNA also requires a reference mixer, which need not be reciprocal.
Keysight's scalar- and vector-mixer calibrations provide you with the tools necessary to determine the characteristics of frequency-translating devices with exceptional accuracy.
