Full Function Microwave Frequency Counters
The Ideal Benchtop Counters
The combination of accuracy, simple operation, and the widest range of standard features and options available ina microwave counter makes the 545B/548B family the best choice for your R&D lab or production test bench. Wherever a microwave counter has multiple duties and a variety of applications to meet, only a full func­tion counter with YIG-tuned preselection can provide the capabilities that you need.
The 545B measures CW, FM and AM frequencies from 10 Hz to 20 GHz, and the 548B extends that range up to 26.5 GHz. With simultaneous power measurement capability, and options for a high stability time base, these high performance counters are ideally suited for applications in:
• Carrier signal measurement
• Transmitter frequency verification
• Channel specific signal measurements
• Production Line testing
• R&D Labs
• ATE
Only Phase Matrix counters offer the unique YIG-preselected heterodyne technique.
Unsurpassed Burnout Protection
Typically found in high performance spectrum analyzers; only Phase Matrix counters feature a YIG-preselected microwave input, which provides unparralled burnout protection, FM tolerance and frequency selectivity. The YIG preselector works like a tunable bandpass filter, preventing harmonics and other out-of-band spurious signals from interfering with measurement of the desired signal. It also protects the counter from accidental application of high level signals (up to 200 watts peak), reducing downtime and the associated high cost of repairing damaged microwave circuitry.
Selective Frequency and Power Measurements
With a single connection, the 545B and 548B can simultaneously measure and display the input signals frequency and power level in the microwave band, eliminating the need for a seperate microwave power meter. Within the 25MHz bandwidth of the YIG-preselector, only the selected signals frequency and power level are measured. Signals to be analyzed are selected by keystroke entry of an individual center frequency, or search a range between a low and high frquency limit. This signal selectivity, combined with 20MHz of FM tolerance at all rates up to 10MHz, allows the 545B and the 548B to make accurate frequency and power level measurements even while the input signal is carrying traffic; there is no need to take the transmitter, or adjacent channels, off the air for routine checks.
