Description

585C/588C/595A/598A Frequency Counter

CW/Pulse Frequency Counter with Peak Power Measurements (available with 595A/598A)

CW, pulsed, and other time-varying microwave and millimeter-wave signals can be automatically measured by the 585C and 588C frequency counters. VCO measurements, chirped radar profiling, and frequency-agile system analysis are all made with unparalleled ease. Pulsed signals can be fully characterized, including carrier frequency, frequency linearity, pulse width, and pulse period. The 585C measures signals up to 20 GHz and the 588C’s range reaches 26.5 GHz with an option to extend to 170 GHz.

All Phase Matrix EIP® brand frequency counters are based on a unique heterodyne architecture that incorporates a YIG-based preselector. The YIG-preselected input provides unparalleled performance, in amplitude discrimination, frequency selectivity, kickback noise, and burnout protection.

Automatic Pulsed/CW Frequency and Power Measurements

1. Automatic Pulsed Millimeter-Wave Counting up to 170 GHz with the addition of the Model 890 cable kit and one or more harmonic mixers. Large amounts of “chirp”, often encountered in millimeter-wave signals, can be precisely counted using Center Frequency Mode.

2. Model 595A/598A Power Measurement Capability operates over the full operating range of the Band 1 and 2 inputs on both CW and pulsed signals.

3. Phase Matrix’s Unique YIG Preselector provides an excellent combination of burnout protection, sensitivity, frequency selectivity and video immunity. The inherent frequency selectivity of the YIG filter allows counting the highest amplitude signal even with many other signals present.

4. Optional Internal Pulse Generator makes the profiling of frequency and power simple and automatic.

5. Pulse Width or Pulse Period can be measured and displayed with a touch of the Pulse Width or Pulse Period key. Pulse repetition frequency can also be easily displayed.

6. Frequency High/Low Limit allows the measurement of a lower amplitude signal in the presence of higher amplitude signals.

7. External Switching Requirements Eliminated by the use of four independent signal inputs that let the operator apply multiple signals and measure any one by merely switching the band selector from the keyboard or over the IEEE-488 Bus.

8. Dual Display For Fast, Easy Readout simultaneously provides two important signal parameters: 1) Frequency to 1 kHz resolution, and either 2) Power to 0.1 dB resolution or 3) Pulse width (or pulse period) to 10 nanosecond resolution. The three-digit (or six digits with special function mode) pulse period/pulse width display utilizes a floating decimal format with annunciators.

9. Automatic Power-Up Self-Testing and Go-to-Local allows one key stroke to switch from remote to local, or to fully initialize the system from local. When initialized, the instrument automatically executes power-up self-tests.

10. Precise Pulse Measurements Provided by the IF Threshold and Gate Outputs. These convenient outputs allow the operator to monitor exactly where within the RF pulse the sample is taken. This feature is especially useful when using external gating for frequency profiling.

11. All Front Panel Functions and Test Sequences Can Be Placed Under GPIB Control via the IEEE-488 bus for ATE applications.

12. Optional Rear Panel Inputs simplify signal routing in rack-mounted applications.

13. External Time Base Reference Capability allows the use of an external 10 MHz reference as a common system time base. Or use the output of the optional ovenized oscillator as the system time base.
