Using the Agilent 81101A
The Output Screen
NOTE
Note that in graphics mode you can only adjust the values of each
parameter, not the parameter format. If you want to change the format of
a parameter, for example O
FFS
-A
MPL
to H
IGH
-L
OW
, you must be in text
mode to select the parameter name with the cursor.
NOTE
When the output is switched on, the instrument monitors the actual
voltage and current levels at the output. The output is automatically
switched off if voltage levels or power dissipation reach levels which
could damage the output circuits.
Normal/Complement Parameter
Switch the output between normal and complement mode:
N
ORMAL
Pulse leading edge rises from low to high level, trailing edge falls from
high to low level.
C
OMPLMNT
Pulse leading edge falls from high to low level, trailing edge rises from
low to high level.
NOTE
This parameter is only available in text mode.
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
Select high and low level formats and automatically set the levels to
the default TTL levels:
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.
