MARKER_READOUT_FORMAT Marker Readout Format. Available readout
formats are:
None = 0
Trace =1
Screen = 2
Table = 3
PORT_x_REF_PLANE_LENGTH Reference Plane Length, where x is the port
number. Returns in units of meter.
TRACE_SMOOTHING_PERCENT Trace smoothing percent. This uses a bit mask
shift, where the bit shift mask is defined as:
PERC_SMOOTHING_BIT_SHIFT 8
PERC_SMOOTHING_BIT_MASK 0xFF
SMOOTHING_PERCENT Current active trace smoothing percent.
CURRENT_LIMIT The limit type (upper/lower) for the active trace.
Upper = 0 and Lower = 1
LIMIT_STATE The limit state (on/off) for the active trace.
On = 0, Off = 1
LIMIT_ALARM The limit alarm (on/off) for the active trace.
On = 0, Off = 1
LIMIT_MESSAGE Limit Pass Fail Message (on/off) for the active
trace. On = 0, Off = 1.
CURRENT_TEMPERATURE The current temperature. Valid only with a cal.
To get the temperature in Celsius divide the
result by 4.
TRACE_x_LP_MODE Low Pass On/Off, where x is the trace number
and a value of
1 implies low pass, and 0 implies off
TRACE_x_LP_RESPONSE_TYPE Low Pass Response, where x is the trace number
and a value of
0 = Impulse, and 1 = Step
TRACE_x_LP_PHASOR_IMPULSE Band Pass Response, where x is the trace
number and a value of
0 = standard and 1 = phasor.
TRACE_x_POLAR_RESOLUTION Linear Polar Resolution, where x is the trace
number. Returned value is 1000 times the
resolution value
TRACE_x_POLAR_REFERENCE Linear Polar Reference value, where x is the
trace number. Returned value is 1000 times the
reference value
TRACE_x_POLAR_REFERENCE_LINE Currently not used
