Introduction

1 – General

This Manual includes:

• Questionnaire to send back together with the instrument 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

Windows

TM

environments. Just execute Windows

TM

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.

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 referring frequency to 9 kHz and reply: f:9 kHz (This value is the

PMM 6630 minimum frequency)

Example of command #63Sf3000000*: Set the referring frequency to 3 GHz and reply: f:3000000 kHz (This value is the PMM 6630 maximum frequency)

Introduction

PMM 6630FOA Fiber Optic Adapter (Optional)

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.
