5.
Press Reset followed by Exec./Ent. on the 2313, to select its listener mode. The
Exec./Ent., Entering and Listen LEDs should light, indicating that the Recorder is
ready for documenting measurements.
6.
If a 7400 Digital Cassette Recorder is connected, activate its Stop key to prevent
recording with the 7400.
7.
A hard copy of the measurement displayed on the 2032 or 2034 will now be ob-
tained each time DIGITAL 1/0 "Plot" is selected on the Analyzer. On completion of
the hard copy, DIGITAL 1/0 "Stop" will be automatically selected. Alternatively, the
copy can be stopped before its completion by pressing DIGITAL 1/0 "Stop".
8.
To deactivate the 2313, press its Reset key. This may be necessary when transfer-
ring data between the 7400 and 2032 or 2034.
Note: If at any time the 2313 fails to respond as described, press Reset and repeat the
particular operation. If correct operation is still not possible then a hard reset may
needed to resume normal operation. See section 3.4.1.
3.7. USE WITH DIGITAL CASSETTE RECORDER TYPE 7400
The Type 7400 Digital Cassette Recorder can be used for long term mass storage of
data transmitted over the interface bus. Up to 500 kbytes of data can be stored on one
tape cassette. As data is formatted according to the ECMA 34 standard, the tape can
be read by other cassette recorders using this standard.
When the 7400 is connected into a system with the 2313, e.g., with a Type 2032 or 2034
as shown in Fig. 3.8, data intended for the 2313 can be recorded on the 7400 and sent
to the 2313 at a later convenient stage.
To record data on tape using the 7400, proceed as follows:
1.
Interconnect the INTERFACE BUS connectors of the 7400 and output device, e.g.,
Type 2032 or 2034 Dual Channel Signal Analyzer, using cable AO 0194 (or
AO 0184 for a 7400 before serial no. 894938), and carry out the necessary prelimi-
nary adjustments to the instruments as outlined in their respective instruction
manuals.
2.
Set the INTERFACE MODE of the 7400 to
"IEC".
3.
Select Power On and set the 7400 to record data by referring to the 7400 instruc-
tion manual.
4.
Activate the read-out of data from the output device. If this is a 2032 or 2034,
ensure that the measurement is displayed on the screen and press the DIGIT AL
1/0 "Plot" pushbutton. Data will then be stored on tape as a
'plot'
file.
Note that data read out of the 2032 or 2034 as a 'plot' file cannot be read back to
the Analyzer. However, by activating the DIGITAL 1/0 "Output", the complete mea-
surement results are read out and can be stored on tape as desired then read
back to the Analyzer at a later stage. This reconstructs the measurement results
on the Analyzer display screen which can be plotted on the 2313 as above.
