Marconi TF 2356 Oscillator
Model TF 2356
Date 1980
Category Measurement instruments
Group Oscillator
Description 20MHz Level Oscillator
                                    Power levels may be measured over a wide range with the 0.1 dB resolution 
digital display in the receiver auto balancing mode or with a 0.01 dB 
resolution combined analogue and digital display in the differential level 

An r.m.s. responding detector is incorporated and level indication is in dBm or 
dB relative to 0.775 V. Frequency is digitally displayed to 10 Hz resolution .

2.	For manual operation the sender and receiver may be operated 
independently. In sequence mode opération, the sender automatically steps 
through a sequence of frequency/level increments. For synchronous 
operation, coaxial cable interconnection permits sender frequency to be 
controlled from the receiver. The addition of optional GPIB* interfaces greatly 
extends the versatility of both instruments and provides two levels of 
programmable operation. Firstly, the sender acts as a bus controller of the 
receiver and, optionally, a Printer. This control capability gives the selective 
level measuring set several powerful modes of automatic operation. 
Secondly, both sender and receiver may be programmed via the bus as part 
of a larger automatic measurement system, in which case the sender's own 
control capability is overridden. Sender versions 52356-301U, -302Y and 
receiver versions 52357-304X, -305M are factory fitted with GPIB interfaces 
but for other versions conversion is a simple retrofitting exercise.

3.	Both instruments may be fitted with an optional rechargeable battery^ 
pack providing approximately 4 hours continuous operation following 
approximately 14 hours charge and the instruments conform to IEG 348 and 
BS 4743 safety regulations.

4.	Application of the instruments may be considerably extended by the 
addition of associated MI bus-controllable instruments. These include a 
coaxial switch unit for scanning up to 56 separate inputs and a baseband 
filter unit to extend the receiver's bandwidth capability to 'blocks' of 
telephone channels from group power measurement up to total baseband
