Name
Time Base Linearity
Delay Jitter
Description
±5%.
Sweep linearity applies over the center eight divisions. Excludes
the greater of either the first
J.1I
division or 25 ns from the sweep
start of the magnified sweep and anything beyond the 100th mag-
nified division.
:5 1 part
in
10,000 (20,000 for 1 ms and slower) + 2 ns, peak-to-
peak during a two-second time
interval. Exclude the first 0.15 divi-
sions
of
the Main sweep.

Description
The typical sensitivities are as follows:
Trigger Source
Noise Reject
HFREJ
LFREJ
AC
Typical Signal Level for Stable Triggering
1.2 divisions from
DC
to
25
MHz, in-
creasing to 2.2 divisions at 150 MHz.
0.5 division or less will not trigger.
0.30 division from
DC
to
10kHz;
attenu-
ates
signals above the upper
-3
dB cut-
off frequency
of
50 kHz.
0.30 division from
100 kHz to 25 MHz,
increasing to 1
.0
division at 150 MHz;
attenuates
signals below the lower
-3
dB cutoff frequency
of
50 kHz.
0.30 division from 350 Hz to 25 MHz,
increasing to 1
.0
division at 150 MHz;
attenuates
signals below the
-3
dB cut-
off frequency
of
160 Hz.
