1230A & 1231A
End of Life Notice:
This product is no longer orderable.
Phase Matrix’s EIP-brand VXIbus 1230A and 1231A are the ultimate pulse and CW microwave frequency counters that feature a YIG-preselected microwave input, which provides unparalleled 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 1231A measures pulsed and CW frequencies up to 20 GHz, and the 1230A extends that range to 26.5 GHz. Options include high-stability time bases and millimeter-wave frequency coverage up to 170 GHz, which makes these counters ideal for applications requiring high performance such as pulse profiling, carrier frequency measurement, pulse parameter measurements, automatic VCO characterization, and frequency agile system analysis.
