6.2.3.1 DSC Self Test
The DSC self test is a thorough test of the entire signal processing chain including the
signal processing computers. Selecting this item will initiate an extensive DSC test and a
printer test (if one is connected). Do not run this test while electro-cautery equipment is in
use. To begin the test:
1. Highlight
DSC Self Test
, then press [SELECT]. The DSC testing screen will display.
2. The following information appears:

The DSC test consists of four sub-tests. The first checks the noise, the second checks
the high-pass filter performance with the amplifiers blocked (fast response), the third
checks the high-pass filter performance with the amplifiers unblocked (high bandwidth),
and the fourth checks the amplifier gains.
The results of each of these sub-tests are displayed for each of the two channels. If any
result is outside the allowed range, the number has an asterisk appended to it. The
allowed range for each of the sub-tests are:
Noise:
0
-
0.24
(µV)
Hi-Pass Blocked:
47.1
-
63.9
(µV)
Hi-Pass Normal:
14.7
-
18.5
(µV)
Gain:
49.2
-
60.2
(µV)
If the Digital Signal Converter is properly connected, the ‘***’ symbols displayed for each
test parameter will change to numeric values for the corresponding channel.
“DSC Test
Results: PASS (or FAIL*)”
message will appear at the end of test. If test fails, check
the connection between the DSC and the monitor, make certain that electro-cautery
equipment is not in use, and run DSC self test again. If the DSC test fails again, the DSC
requires service.
