Chapter 3Operation
Zeroing Sensor
5000-EX
Over time, the sensor’s “zero value” (reading with no applied RF
power) can drift due to environmental factors (temperature,
humidity, etc.) This can make the readings performed by this sensor less accurate by the drift value. If the drift would be a significant
error, re zero the sensor.
1.Ensure the sensor has reached a stable operating temperature.
2.Ensure no RF power is applied to the sensor.
3.Press “Zero” to begin Calibration.
Note:Calibration will take about 40 seconds. Do
not interrupt the calibration! A bar on the screen
will display calibration progress.
4.Do one of the following:
If the calibration is successful, “Cal Pass” or “Calibra-
tion
Complete” will be displayed.
a.Press any key to return to normal operation.
5
If calibration fails, “Cal Fail” will be displayed.
a.Press a key to return to normal operation,
b.Ensure that the WPS is properly connected, and the
RF is off.
c.Rezero. Go back to Step 3.
5000-XT
1.Make sure the sensor has reached a stable operating
temperature.
2.Make sure no RF power is applied to the sensor.
3.Press and hold “0” for two seconds to begin zero calibration.
WARNING
Do not interrupt the calibration.
Note:“Zero/Cal” will be displayed and calibration
will begin.
Note:Zeroing the sensor takes 60 seconds. The
bar graph will display calibration progress.
Note:When complete, “PASS” should be displayed.
4.Press Enter to return to normal operation when zeroing is
complete.
Note:If “FAIL” is displayed, make sure no RF power
is applied to the sensor and perform the procedure
again.

Function Descriptions
Figure 1 Average and Peak Envelope Power -
Square Wave Signal
Average Power
Average power is a measure of the equivalent “heating”
power of a signal, as measured with a calorimeter. It measures the total RF power in the system, and does not depend
on number of carriers or modulation scheme. The WPS is a
broadband sensor that measures power across its entire frequency range. Its diodes operate in their ‘square law’ region
so that the detector output is directly proportional to the
average power, without any additional error correction.
Average power is the most important measurement of any
transmission system since the average power is normally specified on the operating license. It is also valuable as a maintenance tool, showing overall system health, and for calibration.
7
VSWR
VSWR measures the relation between forward and reflected
average power. The Bird Wideband Power Sensor calculates
the VSWR from the Forward and Reflected Average Power
measurements. Rho and Return Loss are also the same measurement, but in different units:
Rho
Rho PRPF=
VSWR
VSWR
1 +
------------=
1 –
Return Loss (dB)
ReturnLoss dB10PRPFlog=
The health of the feedline and antenna systems can be monitored using VSWR measurement under full power operating
conditions. High VSWR is an indicator of feed line damage,
overtightened cable or feed line clamps, or antenna changes/
damage due to weather conditions, icing, or structural damage to the tower.
8
Video Filter
Figure 2 Video Filter Settings, 300 kHz Signal
Except for average power and VSWR measurements, all WPS
measurements rely on a variable video filter to improve accuracy. This filter can be set to either 4.5 kHz, 400 kHz, or full
bandwidth. It should be as narrow as possible while still being
larger than the demodulated signal bandwidth (video bandwidth). Narrowing the filter limits the noise contribution
caused by interfering signals. Listed below are some common
modulation schemes and the appropriate video filter.
Peak power measurements detect amplitude changes as a signal modulates the carrier envelope. The WPS operates in an
asynchronous cycle: 300 ms of waveform sampling followed by
a 50 ms reset period. The peak power is then displayed and the
cycle repeats. The display therefore updates about three times
per second.
Transmitter overdrive can be detected with peak measurements. Common problems are overshoot at the beginning of
burst packets, amplitude modulation, and excessive transients. These damage system components with excessive peak
power and also cause data degradation, increasing the Bit
Error Rate. For TDMA applications, Peak and Burst Power
measurements are used to detect overshoot in single
timeslots. Other timeslots must be turned off for this test.
10
Burst Average Power
Figure 3 Burst Average Power
Burst width (BW) is the duration of a pulse. Period (P) is the
time from the start of one pulse to the start of the next pulse.
Duty cycle (D) is the percentage of time that the transmitter is
on. To calculate the duty cycle simply divide the burst width by
the period (D = BW / P). Low duty cycles mean that the burst
width is much less than the period; a large amount of dead
time surrounds each burst. For low duty cycles, the burst average power will be much larger than the average power.
After peak power is measured, a threshold of ½ the peak is
set. The sampled power crosses that threshold at the beginning and end of each burst. The time between crossings is
used to calculate the duty cycle. Burst Average Power is calculated by dividing the Average Power by the Duty Cycle.
Burst power measurements provide accurate, stable measurements in bursting applications such as TDMA and radar.
Accurately measuring the output signal strength is essential
for optimizing radar coverage patterns. Actual transmitted
power in a single timeslot can be deter-mined in TDMA. The
other timeslots must be off during this test.
11
Crest Factor
Figure 4 Crest Factor - 10 dB CDMA Signal - 100 W
Peak - 10 W Ave
Crest factor (CF) is the ratio of the peak and average powers, in
dB. The WPS calculates the Crest Factor from the Forward Peak
and Average Power measurements.
Crest factor is becoming one of the most important measurements as communication systems move into the digital age. For
CDMA and similar modulation types the CF may reach 10 dB. If
the crest factor is too large, the transmitter will not be able to
handle the peak powers and amplitude distortion will occur.
Crest factor can also detect overdrive and overshoot problems.
Knowing the CF allows end-users to more accurately set base
station power and lower operating costs.
12
Complementary Cumulative Distribution Function (CCDF)
Figure 5 CCDF - 100 W Signal - 80 W Threshold -
20% CCDF
CCDF measures the amount of time the power is above a
threshold. Equivalently, it is the probability that any single
measurement will be above the threshold. The WPS samples
the power over a 300 ms window and compares it to a userspecified threshold, in Watts. The time above the threshold
relative to the total time is the CCDF.
CCDF measurements are most useful for pseudo-random signals, such as WCDMA, where a high CCDF means that the transmitter is being overdriven. CCDF can also detect amplitude
distortion within an envelope caused by unwanted modulating
signals. In TDMA systems, CCDF indicates the health of power
amplifier stages and their ability to sustain rated power over an
appropriate timeframe. As a trouble-shooting aid, CCDF allows
tracking of trends such as amplifier overdrive (which can cause
dropped calls and high bit error rates).
13
Low Repetition Rate Waveforms
Many of today's channel access methods involve the use of
low repetition frequency time division-multiple access
(TDMA) techniques. Examples of these relatively new TDMA
formats include Digital Mobile Radio(DMR), and TETRA systems. The DMR format uses an approach where two discrete
time slots provide access to a single 25 kHz communication
channel, providing the equivalent of 12.S kHz channel bandwidth for the system. The modulation techniques used within
these systems vary, from relatively benign forms of frequency
shift keying, to more complex quadrature formats such as
Quadrature Phase Shift Keying (QPSK).When measuring the
power output of transmitters using the DMR format, the base
station transmitters will normally transmit with both time
slots active, even if there is no traffic on one of the time slots.
Under these conditions, it is a simple matter to measure the
average power of this continuous waveform. When measuring
the output power of subscriber units however, normal operation is to use only one time slot, approximately 30 ms in duration, followed by approximately 30 ms at zero power in the
interval where the other time slot would normally be located.
The remaining waveform resembles a 30 ms burst, occurring
at a 17 Hz repetition rate. Since the measurement of average
power under this condition would result in an unstable reading, the correct measurement would be that of burst average
power. When making this measurement, the sensor will measure the duty cycle of the signal, as well as the average power,
and compute the burst average power of the waveform based
upon these parameters.

Limited Warranty
All products manufactured by Seller are warranted to be free from defects in
material and workmanship for a period of one (1) year, unless otherwise
specified, from date of shipment and to conform to applicable specifications,
drawings, blueprints and/or samples. Seller’s sole obligation under these
warranties shall be to issue credit, repair or replace any item or part thereof
which is proved to be other than as warranted; no allowance shall be made for
any labor charges of Buyer for replacement of parts, adjustment or repairs, or
any other work, unless such charges are authorized in advance by Seller.
If Seller’s products are claimed to be defective in material or workmanship or
not to conform to specifications, drawings, blueprints and/or samples, Seller
shall, upon prompt notice thereof, either examine the products where they are
located or issue shipping instructions for return to Seller (transportation charges
prepaid by Buyer). In the event any of our products are proved to be other than
as warranted, transportation costs (cheapest way) to and from Seller’s plant, will
be borne by Seller and reimbursement or credit will be made for amounts so
expended by Buyer. Every such claim for breach of these warranties shall be
deemed to be waived by Buyer unless made in writing within ten (10) days from
the date of discovery of the defect.
The above warranties shall not extend to any products or parts thereof which
have been subjected to any misuse or neglect, damaged by accident, rendered
defective by reason of improper installation or by the performance of repairs or
alterations outside of our plant, and shall not apply to any goods or parts thereof
furnished by Buyer or acquired from others at Buyer’s request and/or to Buyer’s
specifications. Routine (regularly required) calibration is not covered under this
limited warranty. In addition, Seller’s warranties do not extend to the failure of
tubes, transistors, fuses and batteries, or to other equipment and parts
manufactured by others except to the extent of the original manufacturer’s
warranty to Seller.
The obligations under the foregoing warranties are limited to the precise terms
thereof. These warranties provide exclusive remedies, expressly in lieu of all
other remedies including claims for special or consequential damages. SELLER
NEITHER MAKES NOR ASSUMES ANY OTHER WARRANTY WHATSOEVER,
WHETHER EXPRESS, STATUTORY, OR IMPLIED, INCLUDING WARRANTIES OF
MERCHANTABILITY AND FITNESS, AND NO PERSON IS AUTHORIZED TO ASSUME
FOR SELLER ANY OBLIGATION OR LIABILITY NOT STRICTLY IN ACCORDANCE
WITH THE FOREGOING.
