TGR Series low-cost synthesised RF generators TGR2050 - 150kHz to 2000MHz

Overview

The TGR series are low cost, synthesised RF signal genera
tors that incorporate the essential features required for most
development, test and service work; namely high frequency
accuracy and stability, wide dynamic range, low phase noise
and leakage, and flexible modulation capabilities.

TheTGR2050coversfrom150kHzupto2GHzand incorporates
AM, FM and Phase modulation (internal and external).
The wide frequency range and comprehensive modulation ca
pabilities make it suitable for most tasks within the 2GHz spec
trum.

The TGR1040 has a more restricted frequency range of 10MHz
to 1GHz and incorporates FM modulation only (internal and ex
ternal). It retains the high stability and wide amplitude range of
the 2050 making it suitable for many task including FM radio re
ceiver sensitivity measurements, system gain measurements,
receiver tuning & alignment, oscillator substitutions, EMC/an
tenna/field strength measurements and as a signal source for
many other RF circuit and system development tasks.

Bothinstruments canbe operatedusing eithernumeric orrotary
controls,and can be remotelycontrolled via eitheran RS-232 in
terface or GPIB interface. Ninememoriesare provided for user
set-ups.

TGR1040 - 10MHz to 1000MHz

Lower cost through innovative design

The TGR series sets a new price standard for high performance
RF generators. Advanceddesign techniques utilising the latest
component technologies have made this possible.

Thelow cost makes it possible for every engineer involved in RF
design,manufactureortestingtohaveagenerator of their own.

High Precision and Stability

TheTGR series uses a fully synthesised source locked to a tem
perature compensated crystal oscillator. This provides excellent
signal frequency stability against temperature and ageing. The
TGR2050 adds the further capability of locking to an external
10MHz source.

The frequency can be set to a resolution of 10Hz across the
whole frequency range (1kHz resolution on TGR1040).

Frequency steps can be set to any value and stepping can be
done with up/down keys or the rotary encoder.
The frequency stepping system makes operations such as pre
cise amplitude response characterisation particularly easy.

Wide Amplitude Range & Low Leakage

The TGR series provides an amplitude range of –127dBm to
+7dBm(0·1µVto 500mV into50Ω). Setting resolutionis 0.1dBm
or 0.01µV.

Output level steps can be set anywhere between 0·1dBm and
100dBm (or 0·01µV to 100mV depending on the entry mode).
Steppingthe level is usefulfor quick assessmentofcircuit linear­ity and dynamic range for instance.

The advanced attenuator design provide excellent flatness over
the whole frequency range.

Meticulous internal screening provides very low output leakage
enabling accurate low level measurements in sensitive circuits
such as receivers.

Ease of use

The TGR series incorporates a simple and straightforward user
interface.

The back-lit four line display shows all the major signal parame
terssimultaneously. Data canbe entered numerically using0 - 9
keysorcanbeincremented/decrementedusingup/downkeysor
the rotary encoder. Both frequency and output level can be ad
justed in steps of user programmed size.

Output level can be set either in dBm or linear units of µV or mV.
A single button press will translate from one to the other.

The TGR series can store nine full instrument set-ups in
non-volatile memory. This allows repetitive testing procedures
to be undertaken quickly and accurately.

Comprehensive Modulation

TheTGR2050offers AM, FM andPhase modulation using either
an internal or external source.

Wide modulation range and low distortion make the TGR2050
suitable for most modulated signal test procedures.

The TGR1040 provides FM modulation only using either an in
ternally generated modulator signal or an external signal in the
range 300Hz to 50kHz.

-

This wide bandwidth allows for audio band demodulator testing
as well as LF digital modulation.
