1 General Information

1.1 Introduction

This manual is the operation and maintance manual for the UFX7000A, UFX7900A,

UFX9000/A and J7000 series of Programmable Noise Generating Instruments. It

provides general information plus installation and operation instructions.

1.2 Description of the Basic Unit.

Noise Com, Inc. Series UFX7000A, UFX7900A, UFX9000/A and J7000 represent the

state of the art in Noise Generators. The Instrument can be controller manually by a touch

screen display or remotely via Ethernet, GPIB (IEEE 488) or RS232/RS422/RS423. The

instrument is controlled by a PC104 which provides for a very powerful and user friendly

instrument.

The instrument is 17.22 inches wide, 6.3 inches heigh and 19.5 inches deep. Rack

mounting brackets are optional, and can be fitted at the factory or later by the user.

The RF circuit, without options, is comprised of a noise source, a RF switch, and a

programmable attenuator. The remote interface for this unit with out any options is

Ethernet.

1.3 Options

Options avaliable on the Noise Generator Instruments include :-

GPIB (IEE 488)

Fine resolution attenuator, 0.1dB steps.

Input mains power 240V 50Hz.

Rack mounting brackets, to allow rack mounting into a 4U, 19” rack.

Switching the noise bandwidth by means of band limiting filters. These filters

can be internal or external to the instrument. The frequencies of interest are

specified by the customer. The maximum number of filters for a standard

instrument is 4. The box will be able to provide the full noise band width, the 4

filtered bands, and a terminated (RF off ) position.

Input connector and signal combiner. This allows an external signal to be

combined with the noise output. The noise output for this option is typically 6dB

lower than specified for a standard unit. A resistive combiner is used for low

frequency units (< 2GHz), and a Wilkinson combiner for the higher frequency

units (>2GHz).

A programmable attenuator can be added with the signal combiner option to give

the user amplitude control of the input signal. This attenuator can be 1dB or 0.1dB

steps.

Switched outputs. There is a SPDT RF switch at the output which allows the user

to switch between either of two outputs.

4 Operation

4.1 Operation of Noise Attenuator, and Noise ON/OFF.

Figure 3 shows the start up screen for the UFX9937. The instrument can be fully

controlled using the touch screen interface. Figure 3 shows the screen once the unit has

booted up. {Note: the attenuation maybe different. Under normal shutdown the system

saves the last attenuation setting, and uses this as the start up setting}. The ON/OFF

indicates the state of the noise source. ON = Noise source is on, OFF = Noise Source is

off.

6 Turning Off The Instrument The preferred method of turning the instrument off is to use the Hibernate button in

Figure 3. The Hibernate button is only accessible from this screen. Hibernate saves the

system settings, (e.g. Attenuation, ON/OFF) before the instrument shuts down. These

settings are restored when the instrument is started.

7 Software Up-Grades Software upgrades are avaliable on request. The upgrade is performed using the USB

port, and a flash drive. NOTE: Please read ALL the instructions before performing any

software installation on the instrument.

The following procedure is for installing the new UFX9000A software:

a. Power up the UFX9000A series instrument. When the user interface screen is

present on the instrument, insert the USB removable drive into the instruments

front panel USB socket.

b. Wait for the 'Noise/Com Software" Autorun dialog box to popup.

Note: We have observed that when using the USB removable drive for the first

time, the standard ‘plug-and-play’ messages appear in the lower right corner of

the display. This is normal. When the message reads ‘hardware is now ready...’ a

generic Autorun box appears. If this is your case, remove and reinsert the USB

removable drive from the instrument. The ‘Noise/Com Software’ Autorun dialog

should now appear.

c. Select "Upgrade Noise/Com UFX9000A Software using the program provided on

the device". Click "OK".
