UNIVERSAL

POWER

METERS

The Giga-tronics 8650A
Series Universal Power
Meters have the extensive
measurement capabilities and
unique features required to
test today’s sophisticated
communications systems
faster and more accurately.

TDMA

The 8650A can automatically
measure the average power
of pulse modulated signals or
pulse signals that are ampli-

tude modulated during the
pulse ‘on’ period — such as
TDMA signals.

Using the exclusive Burst
Average Power mode (BAP),
the average power reading in
the pulse burst is automati­cally measured between the
3 dB points. Therefore,the
duty cycle can change in time

without affecting the accura­cy of the meter reading. This
method eliminates the need
to manually set time gating,
which can add errors if the
gate is not set accurately.

GSM

The Time Gating feature of
the 8650A lets you program

The Giga-tronics 8650A Series combines the speed,range and capabilities needed to test today’s sophisticated communications systems.

a measurement start time

average power during a spe­cific time period of a GSM
burst signal. The graphic dis­play provides visual feedback
if you prefer to set the gate
manually. And,of course,
there is the ability to use the
TTL signal for automatically
setting the time gate control.

CDMA

The 8650A has the wide,
80 dB single sensor dynamic
range required for CDMA
signal open-loop tests,the
speed you need to quickly
measure power during
closed-loop tests,and the
10 MHz bandwidth needed
to test third-generation
CDMA signals.

INSTANTANEOUS
PEAK POWER

You can also measure the
instantaneous peak power
level of a pulse modulated
signal with the 8650A.

A built-in delay line lets you
trigger a few nanoseconds
ahead of the pulse for rising
edge measurements. While a
built-in time base gives you
sample delay control up to
100 ms after the trigger
point with 0.5 ns resolution.
And you can view the profile
and see the exact measure­ment point on the pulse.

MAXIMUM PEAK
PO WER

The peak hold feature of the

8650A lets you display the
highest instantaneous power
measured from the time the
feature is enabled until it is
reset.

The display value tracks

the measured value only

when it is rising to a new
maximum;when the meas­ured value falls,the display
value holds at the maximum.

BURST START AND
END EXCLUDE

The exclusive burst start and
end exclude capabilities of
the 8650A allow you to
exclude the beginning or end
of a burst when measuring
the average burst power.

Masking the beginning or
the end of a burst signal,in
order to exclude overshoot
or other distortions,can be
desirable or even required
for certain types of power
measurements.

CREST FACTOR

The crest factor capability of
the 8650A displays the ratio
of the maximum peak power
(peak hold) measurement to
the average power measure­ment (in dB) from the time
the feature is enabled until it
is reset.

The crest factor capability
operates in the same manner
as the peak hold capability:
the display value holds at the
maximum until it is reset.

Unrivaled Accuracy and Built-In Calibration

Giga-tronics uses diode sen­sors exclusively to provide
speed,range, capability and
accuracy unavailable from
any other power meter.

ACCURACY OVER
A 90 dB RANGE

Giga-tronics has solved the
problem that limited the use
of diode sensors to below
–20 dBm — the ‘square law’
region — by utilizing a
patented built-in power
sweep calibration system.

The power sweep calibra­tor uses a 50 MHz amplitude
controlled oscillator to step
from –30 to +20 dBm in
1 dB increments. Each step is
set using an internal thermis­tor — the standard for accu­racy and traceability.

Giga-tronics gives you
thermistor accuracy
plus diode speed for
measuring signals over a
full 90 dB power range.

BUILT-IN
FREQUENCY
RESPONSE
CALIBRATION

Configuring the meter
for measurements is
easy with calibration
factors programmed
into the sensor.

When the measure­ment frequency is
entered,the meter
automatically applies the
correct calibration fac­tor from the sensor
EEPROM. And the
meter automatically
reads a new set of cal factors
when a sensor is changed.

This avoids the chance of
measurement error from
using invalid calibration fac­tors when you change sen­sors,or from forgetting to

An EEPROM in all Giga-tronics sensors
automatically applies the correct cal factor,so
you save time and avoid measurement errors.

enter new calibration fac­tors. You not only avoid
measurement errors; you
also save yourself test time.

The Accuracy Audit table lists the significant uncertainties
of an absolute power measurement. The accuracy of the
8650A combined with the 80301A sensor is compared to a
typical thermocouple sensor/meter combination at +20 dBm,
0 dBm, and –30 dBm (the dynamic limit of the thermocouple
sensor). The uncertainty comparison at –30 dBm illustrates
the accuracy advantage of a wide dynamic sensor, even
when the full 90 dB dynamic range is not utilized.

The Secret is the Sensors

PULSE POWER MEASUREMENTS

Attach a Giga-tronics 80350A Series Peak
Power Sensor to an 8650A meter and
directly measure the instantaneous peak
power level of a pulse modulated signal.

Use the ‘sample delay’ function to set the
desired measurement point on the wave­form. And an external scope can be used
to view the profile and see the exact
measurement point on the pulse.

Giga-tronics power meter architecture pr ovides for a broad choice of functional sensors.
Just by changing a sensor,you can measure CW power,pulse power,and the peak and aver­age power of TDMA,GSM and CDMA signals fast er,more accurately,and over a wider range.

THE
F ASTEST
CW MEASUREMENTS

Giga-tronics 80300A Series CW Power
Sensors let you measure CW power from
10 MHz to 40 GHz at more than 1,750
readings per second over GPIB.

Measure up to 90 dB with a single sensor,
and select from a variety of high power
sensors,up to 50 W.

MODULATED POWER
MEASUREMENTS

The Giga-tronics 80400A Series
Modulated Power Sensors let you
measure the average power of ampli­tude modulated,burst modulated and
other complex modulated signals — such

as TDMA signals — at bandwidths up to
40 kHz.

The Giga-tronics 80600A Series Modulated

Power Sensors provide bandwidth up to

1.5 MHz to measure the peak and average
power of CDMA signals.

Sensor Measurement Capabilities

And the Giga-tronics 80701A Modulated
Power Sensor operating with the 8650A
power meter,provides system bandwidth
up to 10 MHz to measure the peak and
average power of wide band,third-genera­tion CDMA signals over an 80 dB range.

Displays of Intelligence

SEE FOR YOURSELF

The 8650A incorporates a

3.72” wide by 2.15” high
Liquid Crystal Display (LCD)
with 240 x 120 dot resolu­tion,0.38 mm dot pitch,and
Cold Cathode Fluorescent
Lamp (CCFL) back light for
maximum detail and opti­mum viewing.

The large display lets you
see more information. And
the display works in tandem
with the meter controls to
let you view menu selections
and see your input data as
you enter it.

You can view calibration
information,select a standard
mode,setup and recall pre­configured,custom modes,
and set measurement points
and durations.

Each sensor uses an EEPROM to

store values of cal factor.Entering

the measurement frequency

automatically calls up the correct

cal factor.If the measurement

frequency is between cal factor

points, the meter automatically

enters an interpolated value.

An extensive list of help panels

provide assistance in setting up

special features and guidance

in making the measurement.

A volts per frequency input is
available to set the cal factor when
connected to an RF source. As the
source frequency is modified the
V/F output will automatically set
the power meter to the correct cal
factor,thereby eliminating the need
for manual input.

Peak (Pulse) power sensors can be

set to the desired measurement

point of a pulse signal. The trigger

point can be set using an internal

power level or a TTL signal.

Recall setup can be used to
pre-configure measurement
modes for later use. Full
descriptive details help to
clearly identify the settings
before recall.

The graphic display provides visual feedback as you set the
measurement start time and duration of the time gate to
measure the average power during a specific time period.

View the mean power and standard
deviation of the modulated signal
over a time period of interest.
Standard deviation offers an alter­native descriptive analysis of the
power variation when compared to
the traditional crest factor.

STATISTICAL
ANALYSIS

Excessive cost can prove as
detrimental to the success of
communications equipment
as inadequate performance.

The 8650A provides a
range of statistical power
measurement analysis fea­tures that help you optimize
your designs to prevent inad­equate performance due to
under design or excessive
cost due to over design.

These features include
crest factor,standard devi­ation,strip chart, CDF/CCDF,
and histogram,and they let
you view and thoroughly
analyze the power signal
over a selected period of
time.

Combined,they make the
8650A the most advanced
power meter available for
communications systems
design.

The histogram function allows you
to view a power range distribution
over a period of time. The x axis
displays the minimum to maximum
power levels measured during the
interval time period, and the y axis
displays the percent of time each
power level is measured. A zoom
feature lets you view smaller seg­ments of the power range to bet­ter analyze the percentage of time
a specific power level has occurred.

The strip char t function allows you to view the vary-

ing power levels of a signal over a

period of time. The x axis displays

time from the start of the meas-

urement to a selectable period of

1 to 200 minutes, and the y axis

displays the minimum to maximum

power levels measured during the

selected period. Moving a cursor

along the x axis displays time and

the corresponding power level.

The Cumulative Distribution

Function (CDF) shows the

percentage of time a signal is

below a selected power level. The

x axis displays the amount of

power at the selected level,meas-

ured in dBm,and the y axis dis-

plays the percentage of time the

power is at or below the power

specified by the x axis. The

Complementary Cumulative

Distribution Function (CCDF) reori-

ents the CDF curve in accordance

with the equation CCDF = 1-CDF

for more accustomed viewing of a

descending slope. Moving a cursor

along the slope of the curve dis-

plays the power level in dBm and

the corresponding percentage of

time the signal is above that level.
