Verifying the
Installed Drawer
The front-panel controls provide a way to verify whether a drawer
is plugged-in and detected by the 1257. For example, suppose the
following drawer is installed:
1260-CDS
You may verify the installation of these drawer as follows:
1. Press the top key on the keypad next to the display (see
Figure 1-2
). Rotate the knob until the top line reads:
>----OPERATIONS----<
The markers “>” and “<” indicate that this line has been
selected by pressing the corresponding button. When a line
is selected, rotating the knob changes the contents of that
line.
2.
View line 2 (next to top line) by pressing the key just below
top key. The display describes the drawer that is in slot 1:
>----OPERATIONS----<
Drawer: 1260-CDS
Channel: 100
Status: Open
In this example, the drawer is a 1260-CDS. Lines 3 and 4
indicate the status of the drawer (discussed later).
If an installed drawer does not appear on the display using the
technique described, refer to
Appendix C, TROUBLESHOOTING
to correct the problem.
To use the IEEE-488 or RS-232 interfaces to verify the drawer, see
Chapter 5, SCPI COMMAND BASICS
. Look under the heading
Checking for an Installed Drawer
.
Closing a Relay
The front-panel controls may be used to close relays or optical
switches on the drawer. For example, suppose a 1260-CDS
drawer is installed. To close relay channel 4 on this drawer,
proceed as follows:
1.
Press the first key next to the display. Rotate the knob until
the top line reads:
>----OPERATIONS----<
2.
Press the third key to select line 3 of the display:
----OPERATIONS----
Drawer: 1260-CDS
>Channel: 100 <
Status: Open
