Marker Commands 5-49
SR785 Dynamic Signal Analyzer
Marker Commands (Harmonic)
HRMN (?) d {, i}
The HRMN command sets (queries) the Number of Harmonics for display d.
The parameter i is a number of harmonics from 1 to 100.
This command is only valid if the Marker Mode for display d is Harmonic.
HDSP (?) d {, i}
The HDSP command sets (queries) the Harmonic and Sideband Marker Display
for display d.
For Harmonic Marker, i=0 selects the Fundamental, i=1 selects 2xFundamental,
etc. The maximum value of i is the Number of Harmonics.
For Sideband Marker, i=0 selects the Fundamental, i=-1 selects the first lower
sideband, i=1 selects the first upper sideband. The maximum value of i plus or
minus the Number of Sidebands. i<0 is valid only for Sideband marker.
This command is only valid if the Marker Mode for display d is Harmonic or
Sideband.
HRDO (?) d {, i}
The HRDO command sets (queries) the Harmonic and Sideband Marker Readout
for display d. The parameter i selects Absolute (0) or Relative to Fundamental
(1).
This command is only valid if the Marker Mode for display d is Harmonic or
Sideband.
HTHD ? d, i
The HTHD ? command queries the Total Harmonic Distortion for display d. The
parameter i selects percent (0) or dB Relative to Fundamental (1) and is required.
This command is only valid if the Marker Mode for display d is Harmonic.
HPWR ? d
The HPWR ? command queries the Harmonic Power for display d. The returned
value is a real value of Vrms or dBVrms depending on the setting of dB Units>.
This command is only valid if the Marker Mode for display d is Harmonic.
