Miscellaneous Products

  Precision Test Systems also sells the following products:

UMTS / GPS Tester

This product consists of a portable signal generator and a 20 W PA amplifier.  Operating as a pair, they can generate a CW signal from 890 - 960 MHz (GSM band) or 1710 to 2170 MHz (UMTS band) at a power from -40 dBm to +43 dBm (20 Watts).

The FSG960B & PA960B are for the GSM band.

The FSG2170 & PA2170 are for the GSM band.

GSM Controller

The GSMC1, GSM Controller uses SMS messages to allow total control of a remote site from either a central control room or an authorised user’s handheld cellular phone.  One such application is the use by the largest petroleum company in Southern Africa.  The application involves the continued monitoring of various remote sites.

Ultra low phase noise components
 
A new range of ultra low phase noise components are being introduced by Precision Test Systems.  These components are currently used inside many of our products but are now available to the end user as individual modules:

Ultra low phase noise oscillator

This oscillator is a oven controlled oscillator with outstanding phase noise.  The most common frequency is 10 MHz.  Here we make a phase noise is -112 dBc/Hz @ a 1 Hz offset with a -172 dBc/Hz noise floor.  Options to -115 dBc/Hz at 1 Hz offset will be available in the future. 

Other frequencies are available such as 5 MHz.  We are also able to supply a PLL module so many other frequencies can be realized up to 1 GHz.

Ultra low phase noise multipliers and dividers

We now offer our x2 and /2 ultra low phase noise multipliers and dividers.  A typical application is 5 MHz in and 10 MHz out and 10 MHz in and 5 MHz out.  Phase noise is < -130 dBc/Hz @ 1 Hz with a -172 dBc/Hz noise floor.  Gain is 0 dB.

Normal IC dividers cannot achieve this low level of phase noise.

These components are designed for one frequency band.  Frequency bands from 1 MHz to 2 GHz are available.

Applications are RF systems components, up and down conversion, system integration.  Contact us for further details.

New PLL Range

Phase lock loops (PLL) are well proven in industry.  We are experts in designing low phase noise PLL's with or without there own VCO.  We are also working on a digital phase lock loop for ultimate low phase noise performance.  Contact us for further details.
