Offset/Amplitude, High/Low Level Parameters
Set and display the pulse levels in terms of either offset and amplitude, or
high and low level. You can quickly set TTL or ECL output levels using
the S
ET
TTL and S
ET
ECL formats.
S
ET
TTL
Set the levels to the default TTL levels automatically:
TTL-HI:
+2.50 V
TTL-LOW: +0.0 mV
The default levels are set once and can be adjusted afterwards by
moving the entry focus to the values as normal.
H
IGH
-L
OW
Select high and low level format for the pulse levels.
O
FFS
-A
MPL
Select offset and amplitude format for the pulse levels. Offset is
measured from 0V to the middle of the pulse amplitude. Pulse
amplitude is the difference between the high and low levels of the
pulse.
S
ET
ECL
Set the levels to the default ECL levels automatically:
ECL-HI:
850 mV
ECL-LOW:
1.80 V
These default levels are set once and can be adjusted afterwards by
moving the entry focus to the value as normal.
Voltage/Current Mode (mV/V/mA/A)
