Characteristic
Reference information
Performance requirement
LTC Waveform Time Base, typical
3 ms/division for NTSC, 4ms/div for PAL.
Runs in 2 field sweep mode only,
triggered by field one to allow verifying
audio to video synchronization.
Operating Input Voltage Range, typical
13.6 V
p-p
if driven differentially, 6.5 V
p-p
on either input if driven single-ended.
AC coupled so always displayed symmet-
rically about center. Waveform will shift
up or down if overdriven.
Maximum absolute input voltage range
12 V on both inputs.

See
Signal Input-to-Reference Compati-
bility Tables
beginning on page 1--37.
In Ext Ref mode, waveform display and
line select function derive timing from the
Reference input. Reference must have a
frame rate compatible with the input as
listed in the
Signal Input-to-Reference
Compatibility Tables
. Picture mode does
not use timing from the Reference input.
Input Dynamic Range, typical
+ 6 dB range
Absolute Maximum Input Voltage

Timing Shift with 10 to 90% APL Change,
typical
< 0.5 ns
Timing Shift with Hum, typical
< 20 ns with 0 dB hum on WFM mode,
2 degrees on Vector mode.
Lock Range
50 ppm, remains locked.
Lock in Presence of Hum
Bi-level sync
Remains locked with < 1.0 V
p-p
on 0 dB
signal.
Tri-level sync
Remains locked with < 0.5 V
