Features:
- Frequency Range of 10 Hz to 20 GHz and 10 Hz to 26.5 GHz
- 4-Band Frequency Counting
- Operating Temperature from 0 to 50°C
The Phase Matrix 545B/548B CW Microwave Frequency Counters are multi-function microprocessor based devices.
These counters are designed to perform frequency and (optionally) power measurement. The
basic frequency range of the 545B is 10 Hz to 20 GHz, while the 548B extends to 26.5 GHz.
When the 548B is equipped with Frequency Extension Capability (Option 06) and used with
the Phase Matrix 590 and a Remote Sensor, the counter is capable of operating up to 110 GHz.
Frequency counting is divided into four bands. Band 1 is a high impedance input (1 MΩ/20
pF) and covers 10 Hz to 100 MHz. Band 2 is a 50Ω input operating from 10 MHz to 1 GHz.
Band 3 is also a 50 input and covers the range of 1 GHz to 20 GHz using the 545B, and 1
GHz to 26.5 GHz using the 548B. Band 4 is an optional band and covers 26.5 to 110 GHz
and is subdivided into (4) frequency ranges.
An optional power measurement capability (Option 02) has been manufactured to supplement Band 3. With
this option, the counter can simultaneously display frequency to 100 kHz resolution and power
to 0.1 dB resolution from minimum sensitivity up to +10 dBm.
The 548B Phase Matrix CW Microwave Frequency Counter may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
Performs continuous wave microwave frequency measurement with high precision and stability; operates as a bench-top instrument integrating with microwave test setups via standard RF input connectors; interfaces with external controllers through GPIB or RS-232 for automated data acquisition; used in frequency synthesis verification, oscillator characterization, and microwave component testing.
Platforms
Designed for bench-top or rack-mount installation within RF and microwave test systems, interfacing through GPIB and 10 MHz reference input/output for synchronization. Operates under controlled laboratory or production environments to measure continuous wave (CW) microwave frequencies up to 26 GHz with high stability and precision, commonly integrated with signal generators, spectrum analyzers, and microwave amplifiers in telecommunications, radar, and electronic warfare testing applications.
