Chapter 4 Command Reference
[:SENSe] Subsystem
4-90 Programming Guide
• The string “<function> <channel>[,<channel>] ” is returned.
• The string omits default nodes (XNONe) and uses short form mnemonics. If
the channel specifier(s) are set to default value(s), no channel specifier is
returned in response. If the channel specifier(s) are not set to default value(s),
they will be returned in the response with a single space separating the first
channel specifier from the function name.
For example:
– “FREQ” would be returned for frequency on Channel 1.
– “FREQ 2” would be returned for frequency on Channel 2.
– “FREQ:RAT” would be returned for frequency ratio of Channel 1
to Channel 2.
– “FREQ:RAT 1,3” would be returned for frequency ratio of
Channel 1 to Channel 3.
• *RST: “FREQuency 1”
• If the optional channel specification is omitted from the <sensor_function>, a
default channel selection is made. For Frequency, Period, Rise Time, Fall
Time, Pulse Width, Duty Cycle, Totalize, and Voltage Peaks, the default is
Channel 1. For Time Interval, Frequency Ratio, and Phase, the default is
Channel 1 to Channel 2.
• When the sensor function is changed to [:][XNONe:]TINTerval [1,2], the
input routing is set to separate ([:SENS]:EVEN2:FEED “INP2”). Use
[:SENS]:EVEN2:FEED “INP1” to select common-mode Time Interval.
• When the sensor function is changed to Rise Time, the Channel 1 trigger level
is set to 10%, the Channel 2 trigger level is set to 90%, and auto-triggering is
enabled.
• When the sensor function is changed to Fall Time, the Channel 1 trigger level
is set to 90%, the Channel 2 trigger level is set to 10%, and auto-triggering is
enabled.
• When the sensor function is changed to Duty Cycle or Pulse Width, the
Channel 1 trigger level is set to 50%, the Channel 2 trigger level is set to 50%,
and auto-triggering is enabled.
