Introduction

1 – General

This Manual includes:

• Questionnaire to send back to

to service.

• Check list of supplied accessories.

The PMM 6630 is a simple and easy to use RF power
measuring instrument.
It is very suitable in EMC applications to calibrate CDNs
and CLAMPs for conducted and induced immunity tests,
and to measure the power of RF signals forwarded to
antennas or GTEMs cells.
Forward and reflected powers can be measured by using a
directional coupler.
The internal compensation prevents temperature drifting
effects.
The instrument is supplied together with drivers for any
WindowsTM environments. Just execute WindowsTM software
and get your reading (dBm, W and Vrms) into the PC
monitoring window.
If you are using PMM immunity software (conducted or
radiated) all drivers are already embedded and ready to
use.

The PMM 6630 also can work with the optional accessory

PMM 6630FOA that allows to convert the USB signal of the
power sensor into fiber optic compatible signal. It is often
beneficial to use noise immune fibre optic cable instead of
USB cable in environments where is requested a low noise
level or simply to extend the link; moreover, the optic link
is immune to interferences caused by high field level.
The PMM 6630FOA is linked to the USB port of any
Personal Computer through the USB-OC Optical USB
Converter supplied with the unit.

The commands are composed by an ASCII string delimited

by “#” (0x23) and “*” (0x2A)

Commands must start with “#63”.
The answer can be either in ASCII or Binary, according to
the command sent. The first character is always like the
character sent, and can be used as control marker or
synchronization for the answer.

The available commands are of two categories:

• Query COMMANDs

• Setting COMMANDs

The commands have this format:

TABLE 4-1 Query COMMANDs

#63?v* sends back a string containing information about

model, release and date of firmware.

Example of reply to the command #63?v*: "PMM

6630:A.00.01/08;"

#63?p* sends back a string containing power data expressed in

dBm.
When this command is sent while the 6630 is switching the
ADCs, the data is meaningless, thus the 6630 replies with the

string: " *** ".

Example of reply to the command #63?p*: "-4.97 dBm"

#63?m* sends back a string containing the average power of 4

measurements. As for power data, it is expressed in dBm.
When the 4 last data are taken from different ranges, the

average is meaningless, thus the 6630 replies with the string: "
*** ".

Example of reply to the command #63?m*: "-4.97 dBm"

#63?m* sends back a string containing the average power of

16 measurements. As for power data, it is expressed in dBm.
When the 16 last data are taken from different ranges, the

average is meaningless, thus the 6630 replies with the string: "
*** ".

Example of reply to the command #63?M*: "-4.97 dBm"

#63?s* sends back a string containing the serial number of the

6630.

Example of reply to the command #63?s*: "123456789"

#63?f* sends back a string containing the frequency at which

the 6630 is set. Note that this frequency value establishes the
correct calibration of the 6630 at that particular frequency only,
thus when this value has not the appropriate setting, the 6630
measurements are meaningless. It is expressed in kHz.

Example of reply to the command #63?f*: "f:1200 kHz"

When frequency value is set to 0 kHz no frequency correction
factors are computed.
Example of reply to the command when frequency is set to 0

kHz #63?f*: "f:dis"

TABLE 4-2 Setting COMMANDs

#63Sf<value>* sets the frequency(<value>) to which

refer the correction factor. The frequency is expressed in
kHz.
Once the 6630 has received and recognized this command,
all measurements will be corrected using the factor stored
at factory and related to that frequency.
Sending a frequency value of 0 kHz disables the frequency
correction factor function.

Example of command #63Sf9*: Set the referrin
frequency to 9 kHz and reply: f:9 kHz (This value is the

PMM 6630 minimum frequency)

Example of command #63Sf3000000*: Set the referrin

5.7 PMM 6630FOA Fiber Optic Adapter (Optional)

Introduction

The PMM 6630FOA Fiber Optic Adapter is an optional
accessory of the PMM 6630 RF Power Sensor.

The PMM 6630FOA is a fiber optic adapter that allows to
convert the USB signal of the PMM 6630 into fiber optic
compatible signal; it is often beneficial to use noise
immune fibre optic cable instead of USB cable in
environments where a low noise level is required or simply
to extend the link; moreover, the optic link is immune to
interferences caused by high level field.
The PMM 6630FOA is linked to the USB port of any
Personal Computer through the USB-OC Optical USB
Converter supplied with the unit.

The power supply is provided by an internal Li-Ion battery
for up to 8 hours of continuous operation; the internal
battery can be recharged with the battery charger supplied
with the unit.

The PMM 6630FOA has been designed for EMC applications
and can be driven by Win6630 or PMM Immunity Test
software or by a software developed directly by the user.
