Command
:ARM:IMP
Long
:ARM[:SEQuence[1]|STARt][:LAYer]:IMPedance
Form
Set & Query
Parameter Numeric
Parameter Suffix
OHM with engineering prefixes, e.g.: MOHM is Megaohms.
50 Ω
*RST value
50 Ω or 10 kΩ
Specified Limits
Description
Use this command to program the input impedance of the EXT INPUT
connector. Note that only two settings are available. If you try to program
any other value, it will be rounded to one of the specified values.
Example
To set up the input impedance and the triggering threshold of the EXT
INPUT connector:
:ARM:IMP 50OHM
:ARM:LEV 2.5V
Command
:ARM:LEV
Long
:ARM[:SEQuence[1]|STARt][:LAYer]:LEVel
Form

Parameter Numeric
Parameter Suffix
V with engineering prefixes.
*RST value +1.0 V
Specified Limits
–10 V to +10 V
Description
Use this command to program the triggering threshold of the EXT INPUT
connector.
Example
To set up the input impedance and the triggering threshold of the EXT
INPUT connector:
:ARM:IMP 50OHM
:ARM:LEV 2.5V
40
Set EXT INPUT impedance to 50 Ω
