Phase Matrix 1231A Pulsed Microwave Frequency Counter

  • 3-Slot, C-size VXI Module
  • Pulse/CW Frequency Measurement
  • Measure Pulse Parameters
  • Profile Time-Varying Frequencies
  • Exceptional Frequency Selectivity
  • 200 Watt (+53 dBm) Burnout Protection


The EIP/Phase Matrix 123XA brings new capabilities to VXIbus with pulse and CW microwave frequency counters. In only 3 VXI slots, these counters can measure pulsed and CW signals. All are fully compliant with VXIbus specification Revision 1.3/1.4. With the ability to measure pulse widths, pulse periods and time varying frequencies, the 123XA series add high-performance microwave and millimeter-wave measurements to your VXIbus system.

The Phase Matrix/EIP 1231A is the ultimate pulse/CW microwave frequency counters. Designed for demanding applications in R&D, on the production floor, and in maintenance and calibration facilities, these counters bring new levels of measurement capability to your high performance VXIbus applications. Only Phase Matrix counters feature a YIG-preselected microwave input, which provides unparalled frequency selectivity, amplitude discrimination, and burnout protection. These counters also feature the ability to make frequency measurements at a specific point in time on the repetitive signals, simplifying frequency profiling of signals whose frequencies vary with time. The Phase Matrix/EIP 1231A measures pulsed and CW frequencies up to 20 GHz. With options for high-stability time bases and millimeter-wave frequency coverage, these high performance counters are ideally suited for applications such as:

•Pulse Profiling
•Carrier Frequency Measurement
•Pulse Parameter Measurements
•Automatic VCO Characterization
•Frequency Agile System Analysis
