Marker Measurement
SMONitor:RESults:MARKer?
This query command returns a set of values, <string 1>, <string 2>,
<string 3>, <string 4>, and <string 5>, for the marker position.
<string 1> (1 digit) is 0 when all values are within the normal range, or 1 if any
measurement is overranged, underranged or not made.
The definitions and effective ranges of <string 2> (10 digits), <string 3> (5
digits), <string 4> (7 digits), and <string 5> (5 digits) are shown in the table
below. If any measurement is overranged, underranged or not made, the values
9999999999 for <string 2>, 99.9 for <string 3> and <string 5>, and +999999
for <string 4>, are returned.
Marker Position Control
SMONitor:RESults:MARKer:POINt UP|DOWN
SMONitor:RESults:MARKer:POINt <real> [HZ|KHZ|MHZ|MAHZ]
SMONitor:RESults:MARKer:POINt?
This command allows you to move the marker UP or DOWN, or by a numeric
value <real>. The allowable range is from 0 to 400000 (Hz) for the 0 to 400 kHz
span, or from 100000 to +100000 (Hz) for the ±100 kHz span. At preset, this is
set to 1000 (Hz) if Span is set to 0 to 400 kHz, or 100 (Hz) if Span is set to ±100
kHz.
Measurement Range
SMONitor:RANGe 3DBM|+9DBM|+19DBM|+29DBM|+39DBM
SMONitor:RANGe?
This command specifies an absolute power level of Measurement Range. At
preset, this is set to +39DBM. The choices are as follows:
3DBM: The maximum input level is 3 dBm.
+9DBM: The maximum input level is +9 dBm.
+19DBM: The maximum input level is +19 dBm.
+29DBM: The maximum input level is +29 dBm.
Value Definition Range: Span 0 to 400 kHz Range: Span ±100 kHz
