EIP/Phase Matrix Pulse/CW Microwave
and Millimeter-Wave Counters
Automatic Acquisition and Profiling
(Both Frequency and Power) with the Broadest
Frequency Measurement Coverage: 100Hz to 170GHz
585C / 588C full function pulse/CW counters with an
optional internal delaying pulse generator for the
ultimate in ease-of-use
595A / 598A add practical peak and CW power
measurements to the capability of the 585C/588C
Phase Matrix brings to you the broadest spectrum of
pulse and CW microwave and millimeter-wave frequency counters available today. These models offer
automatic and self contained frequency and power
profiling that is ideally suited to such applications as
chirped radar analysis, VCO measurement, and
frequency agile system analysis over a frequency range
up to 170 GHz (depending upon the model selected).
Phase Matrix’s frequency selective heterodyne technique with unique
YIG filter frontend offers benefits not available in any other counter.
Pulsed or CW Measurements to 170 GHz
The 588C and 598A extended frequency capability
enables CW measurements from 100 Hz to 170 GHz, and
pulsed measurements from 250 MHz to 170 GHz.
Parameters such as frequency, power (595A/598A only),
pulse width, pulse period, or PRF can all be measured
fully automatically. The 585C/588C and the 595A/598A
will detect and measure CW, frequency modulated,
amplitude modulated, or pulsed RF signals with pulse
widths as narrow as 50nS.
Automatic Peak Power
The 595A/598A greatly simplify the measurement of
peak power in your application. By measuring the
frequency of the incoming signal, the instrument automatically corrects the power reading for the Calibration
Factor of the internal sensor. You no longer have to
manually enter the Calibration Factors or the measurement frequency. Careful design and internal calibration
tables result in excellent accuracy and repeatability.
Self-Contained Profiling of Frequency
and Power
The optional built in delaying pulse generator enables
completely self-contained frequency and power profiling
measurements. Synchronous outputs on the rear panel
show actual measurement window for viewing on an
oscilloscope. In addition, automatic measurements of
pulse width, pulse period and pulse repetition frequency
simplify your measurement task.
True profiled measurements are possible with a sample
window as narrow as 15nS. Careful design consideration
was given to accurately and automatically measuring
rapidly varying pulse bursts as might be typical in the
generation of frequency hopping or wide band chirp
signals. The Phase Matrix/EIP Model 595A/598A and 585C/
588C actually reacquire the microwave signal for each
measurement window, allowing, essentially, unlimited
frequency changes from window to window. Competitive
techniques require external gating if the frequency
changes more than 10 MHz within the detected burst.

Unmatched Frequency Selectivity
Only Phase Matrix/EIP counters utilize the proven YIG
Preselected Heterodyne Down Conversion technique. This
spectrum analyzer type preselector prevents harmonics
and other spurious signals from interfering with the
measurement of the desired signal. Additionally, it totally
eliminates “kickback” noise. Furthermore, this frequency
selectivity allows the user to select any desired signal for
measurement of both power and frequency in a
multi-signal environment.
Graceful Overload Protection to 200 Watts
The YIG filter provides effective power limiting to protect
against burnout due to accidental application of high-level
signals, yet does not reduce sensitivity. This greatly reduces down time, especially in the hands of unskilled
operators. At remote sites, this high-level burnout protection often proves invaluable by reducing the need for
additional trips if a high power signal is accidentally
connected to the counter’s input.
Full Environmental Compliance
The Phase Matrix/EIP 595A/598A and 585C/588C are in full
EMI/RFI environmental compliance with MIL-STD-461 and
MIL-T-28800, Type III, Class 5. As well as CE certified to
EN50011 and EN50082-1.
Full Programmability
These counters have been optimized for integration into
ATE systems and have all the systems characteristics you
need for your test applications. All front panel controls,
data output format and special functions are controllable
over GPIB. Also, rear panel inputs simplify the integration
of your system.
High Stability Time Bases
All Phase Matrix Counters features the unique YIG Preselected
Heterodyne Down-Convertor.
Optional ovenized time bases provide higher accuracy and
lower cost of ownership. The time base component of error
is dramatically reduced with these high-stability time
bases. The only periodic maintenance required on the
595A/598A and 585C/588C is time base calibration. With
aging rates as low as 2 x 10-7/year, the calibration cycle
can be extended to two years while maintaining kHz
accuracy on a 20 GHz frequency measurement.
Proven Reliability
The predecessors to the Phase Matrix models 595A/598A
and 585C/588C , (EIP 585 and 588, introduced in 1985), have
become standards of reliability, achieving a field proven
MTBF in excess of 40,000 hours. Phase Matrix is so confident in the quality and reliability of these products that we
back them with an optional three year warranty.

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.

Photo 1 shows extreme video distortion
interference on the incoming RF. Photo 2
shows the same RF signal after processing
by the Phase Matrix YIG Preselected
Heterodyne Down-Convertor input filter,
with error causing video component
removed.
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 Limitallows 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.
