Introduction
This section contains detailed information on operating the
Model 7015 and is formatted as follows:
4.2
Maximum signal levels:
Summarizes the maximum
signal levels of the Model 7015 multiplexer card as-
sembly.
4.3
Mainframe control of multiplexer card:
Summarizes
programming steps to control the multiplexer card
from the Model 7001 or Model 7002.
4.4
Multiplexer switching examples:
Provides some typ-
ical applications for using the Model 7015.
4.5
Measurement considerations:
Reviews a number of
considerations when using the Model 7015 to make
measurements.
4.2
Maximum signal levels
CAUTION
To prevent damage to the card, do not
exceed its maximum signal level specifi-
cations.
Do not use the Model 7015 to switch in-
ductive loads, or the solid-state relays
may sustain damage.
To prevent damage to the solid-state relays, never exceed the
following maximum signal levels:
±
175V peak between any two pins, 34mA resistive load,
0.3VA max, 1
×
10
6
V•Hz max.
4.3
Mainframe control of multiplexer card
The following information pertains to the Model 7015 Solid-
State Multiplexer Card. It assumes that you are familiar with
operation of the Model 7001 or Model 7002 mainframe.
If you are not familiar with operation of the mainframe, it is
recommended that you proceed to Getting Started (Section
3) of the mainframe Instruction Manual after reading the fol-
lowing information.
4.3.1 Channel assignments
The Model 7001 has a channel status display (Figure 4-1)
that provides the real-time state of each available channel.
The left portion of the display is for slot 1 (Card 1), and the
right portion is for slot 2 (Card 2). The Model 7002 displays
channel assignments for each card slot, as shown in Figure
4-2.
The Model 7015 card contains 40 channels and is made up
of four banks (Bank A, B, C, and D) of 10 multiplexer inputs
