Fluke 164
2.7 GHz MultiFunction Counter
Fluke’s new MultiFunction
Counter is more than just a
high accuracy top-performance counter; it adds a
wideband DVM and
displays waveform information like an oscilloscope.
Three different
presentation modes let you
VIEW, MEASURE and
ANALYZE your signal.
These presentation modes
supply measuring data, as
seen from different
perspectives, giving more
insight and confidence.
• In the WAVEFORM Mode,
the bright LCD display
shows the input signal
and trigger level, so you
can see that what you are
measuring is correct. At
the same time you can
read off the measurement
which is displayed at up
to 10 digits resolution.
• The VALUES mode
displays up to 10 different
signal parameters
simultaneously, giving a
wealth of information
about the signal being
measured.
• The STATISTICS mode
gives statistical data over
any number of readings
up to 1 000 000, and
reveals trends, jitter, drift,
etc. It reduces random
errors by statistical
averaging, so enhancing
accuracy.
Best of all is the ease-of-operation of
this new instrument. Simple menu
selection and an intelligent AUTOSET
makes everyone an expert user and takes
all the hard work out of getting results.
With just a few keystrokes, the
MultiFunction Counter helps you to
measure more with better results, faster
and with less effort.
Now you can confidently VIEW,
MEASURE and ANALYZE parameters like:
Frequency, Period, Vmax, Vmin, Vpeakpeak, Pulse Width, Rise-/Fall Time, Duty
Cycle, Time Interval, Phase, Burst
Frequency, Vdc, true RMS Vac, Jitter and
Totalize of Counts.
The MultiFunction Counter delivers
high-resolution, high-accuracy readings of
up to 10 digits. Accuracy is enhanced by a
choice of high-stability oscillators,
including TCXO and an ovenized oscillator.
This is the ideal instrument for verification,
alignment, calibration and analysis when
you need accurate results. It is easier to
use than a traditional counter, and more
accurate than an oscilloscope is for timing
and frequency measurements.
• Total signal characterization, with up to
10 parameters displayed
simultaneously.
• 160 MHz / 2.7 GHz frequency counting.
• Up to 10-digits resolution.
• 1 ns single-shot time resolution.
0.01° phase resolution.
• See signals up to 50 MHz and read
voltages, including true-RMS.
• Confident triggering through visual
waveform verification.
• High-stability timebases, including
ovenized crystal oscillator.
• Easy to learn, easy to use, easy to get
results.
• AUTOSET for foolproof results.
• Handheld, rugged, battery operation:
Ideal for field use.
• 3 Years warranty, 40 000 hours MTBF.
• RS-232 interface for programmability
and downloading of data.
• Optional FlukeView®for Windows®to
analyze, document and store your
results.

Technical Data
1
New technique captures
fast transitions more
effectively
Figure 1a shows the MultiFunction
Counter’s Transitional-Sampling™. From
the start trigger point, many time intervals
are measured at different trigger levels,
scanned over the entire waveform. This
technique concentrates sample data on
transitions, where high time resolution is
most needed. Vertical resolution is defined
by the 8-bit trigger level DACs, supplying
256 vertical steps.
Figure 1a. This drawing shows how the
MultiFunction Counter’s unique Transitionalsampling™ concentrates sample data on
transitions, obtaining a high time resolution of
<1ns in all time base positions (>1 GSa/s
effective sample rate).
Figure 1b. By comparison, this drawing shows
Time Sequential sampling, which is
traditionally used in DSOs. Only a few samples
are taken on transitions, creating the risk that
very narrow pulses will be missed.
Unique capabilities to
measure Low Duty Cycle
signals
Unlike DSOs, Transitional-Sampling™
resolution does not depend on time-base
settings, and captures down to 6 ns
narrow pulses with < 1ns time resolution
at all time-base settings. This offers a
unique capability to measure low duty
cycle signals. For example, figures 2a and
2b show a 1 µs radar pulse. Figure 2a
shows two cycles of the 1 ms pulse period,
while simultaneously the pulse width is
measured with 5 digits resolution.
Figure 2b views the pulse shape, while
the frequency (or another parameter) is
measured with very high accuracy.
WAVEFORM presentation mode
Figure 2a. Despite a 1÷1000 low duty cycle,
the MultiFunction Counter displays the pulse
width with high accuracy.
Figure 2b. This screen shows all the pulse
details yet is 1000 x faster than in figure 2a.
Simultaneously the frequency is measured
with 10 digits resolution.
VALUES presentation mode
Figure 2c. In the VALUES presentation mode,
all signal parameters can be shown
simultaneously, without the need for setting
changes per measurement. Any parameter
can be selected as “primary”, to be displayed
at the top of the screen in large numerals and
with full resolution.
Analyze with Statistics
A single keystroke gives statistical data
such as the Mean, Maximum, Minimum,
Max-Min and Standard Deviation of a
number of samples. By definition, the
Standard Deviation of Time Interval
samples gives the RMS jitter. The Max-Min
represents the peak-peak jitter. For FM
frequency measurements, the Max-Min
returns the peak-to-peak deviation of the
frequency, while MEAN gives the carrier
frequency.
STATISTICS presentation mode
Figure 2d shows how STATISTICS reveals
much more about the signal than a single
measurement ever could. E.g. jitter, drift,
wander or modulation.
VALUES presentation mode

Accurate Phase
Measurements
Figures 3a and 3b show how a MultiFunction Counter performs, where by
contrast both a Phasemeter and a scope or
DVM would be required.
Figure 3a. The signal on channel B represents
the output signal from a filter network, that is
delayed in phase with respect to the input
signal A.
Figure 3b. The Vp-p values of the output and
input signals indicate a ratio of
439mV ÷ 629mV = 0.7 i.e. at the frequency
where the output signal B is 3dB down versus
the input signal A. The frequency and the
phase delay are measured simultaneously
with high accuracy.
Advanced trigger features
The Model 164’s special trigger features
enable you to capture a particular signal
out of a stream of pulses, by ignoring
unwanted signals. An example would be
measurements on mechanical relays and
switches. Contact bounce at the beginning
of the signal does not normally allow a
traditional counter to measure the pulse
width digitally. Start and stop at the first
trigger event would result in an erroneous
measurement of only the first bouncing
contact closure. Trigger Hold-Off enables
the MultiFunction Counter to ignore “stoptriggering” over a pre-settable time of
200 ns to 1.6 s.
Figure 4. Despite contact bounce, the relay”ON” time is measured, thanks to the set 5 ms
trigger Hold-Off time. This allows accurate
adjustments of relays and switches.
Frequency Measurements
with Error-free triggering
Frequency measurements on basic signals
are best made with AUTO Trigger.
Figure 5a. The MultiFunction Counter gives
correct results even on a noisy signal. AUTO
Trigger centers the trigger level at 50% of
amplitude and adjusts the trigger hysteresis
band (noise immunity band) to 33% of the
input amplitude to provide optimal noise
immunity.
Figure 5b. By comparison, this figure shows
how too high a sensitivity in a traditional
counter could give erroneous results. Too high
a trigger sensitivity means that noise forces
the input signal to cross the trigger level (very
narrow hysteresis band) more than once per
input cycle and cause false counts.
3
Manual Trigger
Special applications with composite or
complex signals often require manual
trigger setting. The MultiFunction Counter
gives full control over triggering. The
trigger level can be set and is visible as
cursor-lines on the waveform, see figures
6a and 6b.
Figure 6a. Frequency measurement with
manual trigger level setting, where only the
last pulse in each pulse-burst triggers the
counter. This means you can measure the
repetition frequency of the burst reliably.
Figure 6b. When making a pulse width
measurement, for instance to check the
linearity of a DAC, the trigger level can be set
and monitored to accurately measure the pulse
width at each step on a stair case signal.
Automatic Burst
Measurements
Amongst frequency measurements,
measurements on bursts are the most
difficult ones to perform. One may want to
measure the pulse- or carrier frequency
inside the burst i.e. the “Burst frequency”,
or the “Burst repetition frequency”. The
MultiFunction Counter is unique in
offering fully automatic triggering on
burst signals.
Burst frequency
Burst frequency measurements require a
measurement that is synchronized with
the presence of the burst. Some counters
feature external arming and arming delay
to synchronize the start of a measurement
with an external signal. A requirement is
that the measuring time be set shorter
than the burst duration and that the
counter has a high resolution to obtain the
accuracy required. The MultiFunction
Counter measures Burst Frequencies fully
automatically.
Burst repetition frequency
Burst repetition frequency measurements
require that only one count per burst is
counted. Trigger Hold-Off can prevent a
counter from being triggered more than
once per burst. Figures 7a and 7b show
how the MultiFunction Counter
automatically measures both the Burst
Frequency (cycles inside the burst) and the
Burst Repetition Frequency. Thanks to the
high resolution, the readout is in 6 digits
despite the fact that the “narrow” burst of
106µs contains only 12 cycles.
Figure 7a. An automatically measured burst
frequency of 113.449 kHz.
Figure 7b. The MultiFunction Counter
measures automatically and shows
simultaneously both the burst frequency and
the burst repetition frequency.

derived from the input signal (in figures 4a
and 4b) by the green AUTO SET button.

By pressing the INFO key,
On-Line information is given on any
function or setting that is selected by the
On-Screen cursor. A built-in Tutorial gives
an overall explanation of the MultiFunction
Counter, eliminating the need to carry a
manual on-site.

Additional Trigger Control
Normally, measurements are immediately
started/stopped by the first input event
that meets the trigger conditions. Arming,
Arming Delay and Hold-Off are additional
trigger control features that enable the
counter to measure at a specific point in a
stream of pulses on input A, by ignoring
triggering during a set delay time and/or
as long as an additional trigger condition
on input B has not been fulfilled.
Arming ON: Start triggering is enabled
directly after an external arming signal has
triggered the arming input B. Applies to
Frequency, Period or Pulse Width
measurements.
Start Arming Delay: 200 ns to 5s. After
arming, an additional delay is inserted
before the instrument can be starttriggered for a new measurement.
Trigger Hold-Off: 200 ns to 5s. Stop
triggering is inhibited during the set trigger
Hold-Off time. Applies to Time Interval,
Pulse Width, and Rise/Fall Time
measurements.

Measurement
Uncertainty examples in table 1 and table
2 are a simplified way to quickly obtain
the magnitude of accuracy for commonly
made measurements. The figures are
overall figures, taking into account all
instrument error-contributors, such as
quantization error, trigger errors, reference
crystal oscillator ageing, temperature drift
and one year calibration interval.
Reference is made to the Users Manual, for
exact calculations of the measurement’s
uncertainties (random, systematic and total
values), taking into account specific
manual settings, ambient temperature and
input signal characteristics such as slewrate and noise.
Frequency measurements on Sinewave
signals
Table 1 shows the uncertainty for
measurements on undistorted 1Vrms
sinewave input signals, with instrument
settings obtained through AUTOSET and
making use of the internal time-base
reference at room temperature.
Conditions that lead to a better accuracy
(reduced uncertainty) are: steeper trigger
transitions (for instance through higher
input amplitude and higher input
frequency), use of STATISTICS to average
the result of a number of readings, the use
of a more accurate external time-base
reference and a shorter calibration interval
than 12 months. In LF Frequency
measurements, the internal trigger
uncertainty is the dominant error
contributor, whereas for HF Frequency
measurements the internal time-base
uncertainty dominates.
Frequency and timing measurements on
Pulse input signals
Table 2 shows the uncertainty for
measurements on undistorted 1Vp-p pulse
signals with 10 ns rise/fall times (except
for rise/fall-time measurements, where
noted differently), with instrument settings
obtained through AUTOSET and making
use of the internal time-base at room
temperature.
Conditions that lead to a better accuracy
(reduced uncertainty) are: steeper trigger
transitions (for instance through shorter
rise/fall time and higher input amplitude),
use of STATISTICS to average the result of
a number of readings, the use of a more
accurate external time-base reference and
a shorter calibration interval than 12
months. For short duration Time
measurements, the 1 ns resolution is the
dominant error-contributor, whereas for
long duration Time measurements, the
internal time-base uncertainty dominates.
