Specification—442 Service
Table 1-1 (cont)
Characteristics Performance Requirements Supplemental Information
VERTICAL SYSTEM (cont)
CMRR (DIFF Mode) At least 10:1 at 1 MHz in
10 mV/div (IX window) position
for common mode signals of
8 divisions or less with gain
adjusted for best CMRR at
50 kHz.
HORIZONTAL DEFLECTION SYSTEM
Sweep Rate
Calibrated Range
0.5 s to 0.1 jus/div; 21 steps
in a 1-2-5 sequence.
Uncalibrated (VAR)
Range
Continuously variable between
calibrated settings. Decreases
sweep rate by at least 2.5:1.
Extends slowest sweep rate to
at least 1.25 sec/div.
Accuracy
+20° C to +30° C
Sweep accuracy applies over the
center 8 divisions. Exclude the first
50 ns of sweep for both magnified
and unmagnified sweep rates as well
as anything beyond the 100th
magnified division.
Unmagnified
Within 3%.
Magnified
Within 5%.
—15°C to +55° C
Unmagnified Within 4%.
Magnified
Within 6%.
X10 Magnifier
Extends fastest sweep rate
to 10 ns/div.
10:1 (in X10 position—
with button pressed in— the sweep
rate is one tenth of that indicated
for the SEC/DIV switch setting).
X-Y Operation
X-Axis Deflection
Accuracy 5-division reference signal.
+20° C to +30° C ±5% (MAGNIFIER in XI only).
-15°C to +55° C
♦
±6% (MAGNIFIER in XI only).
Sensitivity Same as for Channel 1 and
Channel 2 Calibrated Deflection
