KXCI command strings for scope card
ZTEC function: SCP2:
SCP2HR:
Example: Query the horizontal and timebase settings:
:SCOPE:HORIZ?
Trigger Query
KXCI command: :SCOPE:TRIG?
Purpose: Query the edge trigger settings.
Returned values: triggerSource - Source used to trigger the scope:
level - Analog trigger level (in volts). This is only used for Channel 1 or Channel 2 as the trigger source:
Full-scale range value
slope - Activating edge of the selected trigger:
0 = Falling
1 = Rising
mode - Trigger mode:

ZTEC function: SCP2:
SCP2HR:
Example: Query arm settings:
:SCOPE:TRIG?
Vertical Query
KXCI command: :SCOPE:VERT? channel
Purpose: Queries the vertical settings for the selected channel. The Returned values are for the selected input
channel.
Parameters: channel
Selects the input channel.
Returned values: range - Full-scale acquisition range (in volts).
offset - DC offset voltage that is represented at vertical center.
coupling - Input coupling:
0 = AC
1 = DC
impedance - Input impedance:
lowpassFilter - Lowpass filter:
Note: If the high-resolution scope card (Model 4200-SCP2HR) is installed, the returned value for will be
