Programming Command Reference
SMONitor Subsystem
• +39DBM: The maximum input level is +39 dBm.
Measurement Result
SMONitor:RESults?
• If the 0 to 400 kHz span is selected, this query command returns a set of test
result values, <string 1>, <string 2>, <string 3>, <string 4>,
and <string 5>.
o <string 1> (1 digit) is 0 when all measured results are within normal range,
or 1 if any measurement is overranged, underranged or not made.
o The definitions and effective ranges of <string 2> (10 digits), <string 3> (5
digits), <string 4> (5 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> and −99.9 for <string 3>, <string 4> and
<string 5>, are returned.
• If ±100 kHz is selected, this query command returns a set of test result values,
<string 1>, <string 2>, <string 3>, <string 4>,
<string 5>, and <string 6>.
o <string 1> (1 digit) is 0 when all measured results are within normal range,
or 1 if any measurement is overranged, underranged or not made.
o The definitions and effective ranges of <string 2> (10 digits), <string 3> (5
digits), <string 4> (5 digits), <string 5> (5 digits), and <string 6> (5 digits)
are shown in the table below. If any measurement is overranged,
underranged or not made, the values 99999999999 for <string 2> and −99.9
for <string 3>, <string 4>, <string 5> and <string 6> are returned.
