Information
INTRODUCTION
Digital Synchronizer TF2171 is designed for use with Signal Generator
TF2015, to which it can be fitted as shown in Fig. 1.1. Together, the
instruments provide a 10 to 520 MHz signal Generator system with high
discrimination tuning and very good frequency stability.
Warm-up drift is eliminated, so measurements can be commenced almost
immediately after switching on. Incremental frequency control can be
obtained digitally by adjusting the frequency switches of the synchronizer in
increments of 100 Hz up to a maximum of 0.5% of the initially set frequency
without any readjustment of the Generator.
The synchronizer can also be switched to provide a 1 MHz standard
frequency or to accept an external 1 MHz Frequency Standard.
The setting up procedure is extremely simple and calls only for the
positioning of the synchronizer frequency switches and the tuning of the
signal Generator to obtain a 'locked-on' condition.
All the features of Signal Generator TF 2015 are fully maintained including
the a.m. and f.m. facilities and the synchronizer can be switched to allow the
Generator to be used independently i.e. in the unlocked mode.
