PULSE Multi-analyzer System Type 3560-B/C/D/E – Installation and IDAe Hardware70
6.3 5/1-ch. Input/Output Controller Modules Types 7537,
7537-A, 3560-B-010, 3560-B-020
This module comes in two versions: Type 7537
with LEMO connectors on the input channels and
Type 7537-A with BNC connectors. Type 3560-B-
010 is equivalent to Type 7537, while Type 3560-B-
020 is equivalent to Type 7537-A. For input of sig-
nals in seven ranges from 7.071 mV to 7.071 V
peak
in 10 dB steps plus 12 V
peak
over the frequency
range to 25.6 kHz.
6.3.1 Common Features
Output 1
BNC connector (see Fig.7.5 on page 90) for output
of a high-quality sine tone in the frequency range
0.1 Hz to 25.6 kHz. The maximum output voltage is
5V
rms
delivered in one output range through a 24-
bit D/A converter. Output may be grounded or
floating, controlled by PULSE software.
Tacho
BNT connector (see Fig.7.3 on page 89) capable of providing power for tacho probes. This
is connected in parallel with Input 1.
Multi Frame Control and Synchronisation
This is used for switching the front-end on and off remotely so that pressing any power
button on any front-end will power up all front-ends.
The connector is also used for multiframe control via AES/EBU. Connect all the frames
together with 50 Ω termination
a
at both ends using standard 50 Ω cables of maximum length
100 m. The AES/EBU protocol contains both clock and sync. signals as well as power
control. See “AES/EBU and Types 7536, 7537, 7538, 7539 and 7540” on page 16.
A circular LED around the Multiframe Control BNC socket indicates measurement status
(red: digital error; green: normal operation; flashing yellow: synch. signal; flashing red/
green: program download).
Aux. I/O
See section 7.1.
a. A 50 Ω termination is built into these modules and is activated when First or Last Frame is set to Yes.
