HP 5361B
Pulse/CW Frequency Counter, 20GHz
The Agilent Technologies 5361B offers both high-precision pulse and CW
performance up to 40 GHz. With built-in frequency modulation profiling,
the 5361B characterizes radar, EW, and communications systems or components.
The counter makes complex measurements for the carrier frequency of agile
signals, staggered PRIs, or the frequency transients in a pulsed or CW
signal. It can be used to characterize radar pulses or test a Stable Local
Oscillator (STALO). Functions for measuring step response, post-tuning
drift, and settling time facilitate accurate and easy testing of VCOs
and DTOs.
The 5361B helps lower your equipment costs by eliminating the need for
a separate CW counter, pulse generator and computer, and is a cost-effective
choice for manufacturing and R&D. High-speed throughput saves operator
time, and periodic maintenance is limited to time base calibration.
Features:
- Precise pulse measurements to 20, 26.5, or 40 GHz.
- PROFILE function characterizes frequency transients, modulation (such
as chirp), and linearity.
- Simple-to-use automatic functions include calibration, pulse averaging,
and measurement display.
- Scope-View provides confidence and easy setup for externally gated
measurements.
- Fast track measures a signal sweeping up to 800 MHz per second.
- Low FM rate allows measurement of signals that vary slowly in frequency.
