(
short handle,
PS3000A_CHANNEL channel,
short enabled,
PS3000A_COUPLING type,
PS3000A_RANGE range,

)
This function specifies whether an input channel is to be enabled, its input coupling
type, voltage range, analog offset and bandwidth limit.
Applicability All modes
Arguments
handle,
the handle of the required device
channel
, the channel to be configured. The values are:
PS3000A_CHANNEL_A :
Channel A input
PS3000A_CHANNEL_B :
Channel B input
PS3000A_CHANNEL_C :
Channel C input
PS3000A_CHANNEL_D :
Channel D input
enabled,
whether or not to enable the channel (
TRUE
or
FALSE
)
type,
the impedance and coupling type. The values are:
PS3000A_AC:
1 megohm impedance, AC coupling. The channel
accepts input frequencies from about 1 hertz up to its maximum -
3 dB analog bandwidth.
PS3000A_DC:
1 megohm impedance, DC coupling. The scope
accepts all input frequencies from zero (DC) up to its maximum
-3 dB analog bandwidth.
range
, the input voltage range:
PS3000A_50MV :
±50 mV
PS3000A_100MV :
±100 mV
PS3000A_200MV :
±200 mV
PS3000A_500MV :
±500 mV
PS3000A_1V :
±1 V
PS3000A_2V :
±2 V
PS3000A_5V :
±5 V
PS3000A_10V :
±10 V
PS3000A_20V :
±20 V
analogueOffset,
a voltage to add to the input channel before
digitization. The allowable range of offsets depends on the input
range selected for the channel, as obtained from
ps3000aGetAnalogueOffset .
