Double Pulse
3.6.2 OUTPUT Menu
The Output menu enables the pulse high and low levels to be set. The levels are limited by four factors:
- The absolute limits are ±10 V.
- The high level must be greater than the low level.
- The pulse amplitude must be between 0.1 V and 10 V p-p, into 50
Ω.
- The levels cannot exceed the limits as set in the OUTPUT LIMITS menu.
Output Menu
F1: HILVL - Selects the pulse high level voltage.
F2: LOLVL - Selects the pulse low level voltage.
F3: PREDEF - Selects predefined pulse output levels. In addition to being able to set the levels to any
value within the limits, the user may also select one of four pre-defined levels:
CMOS: Low level (LOLVL) = 0 V, High level (HILVL) = 5 V
TTL: Low level (LOLVL) = 0.4 V, High level (HILVL) = 2.4 V
ECL: Low level (LOLVL) = -1.8 V, High level (HILVL) = -0.8 V
USER: User-defined levels, entered by using the USER menu (F5: HIPRED and
LOPRED) Press OUTPUT to exit USER menu.
