SERIAL NUMBER OF THE INSTRUMENT
You can find the Series Number on the rear panel of the instrument.
Series Number is in the form: 0000X00000.
The first four digits and the letter are the Series Number prefix, the last five digits are
the Series Number suffix. The prefix is the same for identical instruments, it changes
only when a configuration change is made to the instrument.
The suffix is different for each instrument.

1.3 Introduction
The PMM 6600 is a simple and easy to use RF power measurement
solution.
It has been mainly designed for EMC application in order to calibrate CDNs
and CLAMPs for conducted and induced immunity tests, or to measure
input power forwarded to antennas or GTEMs cells.
Using a directional coupler the forwarded as well the reflected input power
can be also measured.
Thanks to his internal temperature compensation, temperature drifting
problems are overcome.
NARDA supply simple but powerful drivers to be used with any WindowsTM
environments.
Just execute WindowsTM software and get your reading (dBm or Watt) into
the PC monitor.
If you are using PMM immunity software (conducted or radiated) all drivers
are already embedded and ready to be used.

display
3.3 To connect
PMM 6600 input
to source
Before starting to use the PMM 6600 RF power meter, provide for a correct
hardware and software installation as recommended in Section 1.
By default software driver recognizes automatically PMM 6600 if
connected at COM 2 serial port.
If this serial port is already busy, click once on PMM 6600 icon and open
Property window from Program Manager in Windows TM 3.11, or select the
icon with the right mouse button and choose Property from menu in
Windows TM 95, add the command COMM=N preceded by a space (in
capital letters) at the end of the Destination field where N indicates the
serial port to be used. Then confirm by selecting Apply.
The assigned COM port nr. must be between 1 and 9.
In other operating system the Destination field is enclosed in double
quotation marks (“); in this case, the command COMM=N, preceded
by a space must be outside.
From Program Manager click on PMM 6600 icon. The software will then
prompt:
Connect the PMM 6600 input connector to the source you want to
measure.
The display will show the measured power expressed both in dBm and in
Watt.
Click EXIT if you want to terminate.
Be sure not to apply more that 1 Watt to PMM 6600 input. A
permanent damage could occur.
Make sure that PMM 6600 input connector is well tight to the source N type
RF connector. Grounding problems can cause wrong readings.

Maintenance and Servicing 4-1
4 - Maintenance and Servicing
4.1 Return for service If the instrument should be returned to NARDA for service, please
complete the service questionnaire enclosed with the User Manual and
attach it to the instrument.
To minimize the repair time, be as much specific as possible when
describing the failure. If the failure only occurs under certain conditions,
explain how to duplicate the failure.
If possible, use of the original package to ship the equipment is preferable.
In case other package should be used, ensure to wrap the instrument in
heavy paper or plastic.
Use a strong shipping container together with enough shock absorbing
material all around the equipment, to provide a firm cushion and prevent
movement in the container.
To prevent damage during shipment in particular protect panels with
display and connectors.
Seal the shipping container securely.
Mark the shipping container FRAGILE to encourage careful handling.
4.2 Equipment cleaning
Use a non abrasive clean, soft and dry cloth for equipment cleaning.
To clean the equipment do not use any solvent, thinner, turpentine,
acid, acetone or similar matter to avoid damage to external enclosure.

Serial Communication Protocol 5-1
5 - Serial Communication Protocol
5.1 RS 232 Protocol
A reading of the measured RF power levels through any different software
application can be also available using the following specifications to
communicate via RS 232 with the 6600 Power Meter:
•the communication is asynchronous and half duplex, where the
computer is the master and the 6600 can only be the slave
•the Baud Rate is 9600 with 8 bit for each string, 1 stop bit and no parity
bit
•the length of the strings is fixed, using the usual ASCII code from 00 to
127 (8FH); in dual configuration 6600+6600D, each string of the
Primary unit (6600) starts with “#PM” and ends with “*”; instead, each
string of the Secondary unit (6600D) starts with “#SM” and ends with
“*”.
By now the RF Power meter recognises up to 3 requests sent by the
computer:
#PMV*
#SMV*
to know type and firmware release number of the
instrument;
For the Primary unit, the answer is “ PMM6600 Vx ”, where
“ x” is the firmware release
#PMp*
#SMp*
the answer are 2 bytes (H, the first transmitted, and L) to
calculate the measured CW power (without modulation)
#PMP*
#SMP* the answer are 2 bytes (H, the first transmitted, and L) to
calculate the measured modulated power
5.2 Calculation of Power The Power P have to be calculated as per the following formula:
Example:
At the enquiry “ #Pmp “ the 6600 answers “ 03H ” and “ 3FH” (3 and 63 in
decimal), then the CW power (or the power without modulation correction)
is
