MATH[1]:VERTical:SCAle
Arguments
<NR3> is a floating point number that specifies the vertical channel scale in
units-per-division. The value entered here is truncated to three significant digits.
Examples
CH4:SCALE 100E-03 sets the channel 4 scale to 100 mV per division.
CH2:SCALE? might return :CH2:SCALE 1.0000 indicating that the current scale
setting of channel 2 is 1 V per division.
CH<x>:TERmination
Sets the connected-disconnected status of a 50 Ω resistor (or 75 Ω with
MDO3000 models) which may be connected between the specified channel's
coupled input and oscilloscope ground. The channel is specified by <x>. There is
also a corresponding query that requests the termination parameter and translates
this enumeration into one of the two float values.
NOTE. 75 Ω termination is not available on the MDO3104 or MDO3102 models.

Syntax
CH<x>:TERmination {FIFty|MEG|<NR3>}
CH<x>:TERmination?
Arguments
FIFty sets the channel <x> input resistance to 50 Ω.
MEG sets the channel <x> input resistance to 1 MΩ.
<NR3> is a floating point number that specifies the channel <x> input resistance
numerically.
Examples
CH4:TERMINATION 50.0E+0 establishes 50 Ω impedance on channel 1.
CH2:TERMINATION? might return :CH2:TER MINATION 50.0E+0 indicating
that channel 2 is set to 50 Ω impedance.
