HP 5361B Pulse/CW Microwave Counter

The HP 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 service. High-speed throughput saves operator time, and periodic maintenance is limited to time base calibration.

• Precise pulse measurements
• 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

  Precise pulse measurements

  Measure frequency, PRF, PRI, pulse width and off-time.

  PROFILE function

  Innovative gating circuitry provides fully automatic profiles of complex frequency modulations such as chirped radar. Hardcopy output of the frequency profile is available via a direct printer interface.

  Simple-to-use

  The Auto-Suite group of tasks are performed automatically by the 5361B. Most competitive equipment automates only a smaller subset of measurements.

  Scope-View

  For externally gated measurements, there is always a concern that the gating signal may not coincide with the microwave pulse. Scope-View enables you to easily set up an externally gated measurement by letting you see the downconverted pulse with a dc offset at the actual measurement interval.
