TMAX:SCAN
Timing Measurement Analyzer parameter query
Class DVI/HDMI Signal Analyzer
Description Retrieves the measured value of the parameters queried of the last timing test run. The
timing parameters can be read back via queries using the following commands
Query syntax TMAX: parameter?
parameter
The parameter name (see table above)
Example
PNSF 1 // Pseudo-random noise signal format set to MEASURED
PNST 1 // Pseudo-random noise signal type set to QDI-BCM
TMAU // Measure external signal’s timing format parameters
TMAX:SCAN? // Queries for the SCAN parameter that was measured
TMAX:HRAT? // Queries for the HRAT parameter that was measured
SCAN ? Returns the scan type
PRAT? Returns the pixel rate (in Hz)
VRAT? Returns the vertical (field) rate (VRAT = FRAT * SCAN)
HTOT ? Returns the horizontal total (in pixels)
HRES ? Returns the horizontal active (in pixels)
HSPD ? Returns the horizontal sync pulse delay (in pixels)
HSPW ? Returns the horizontal sync pulse width (in pixels)
HSPP ? Returns the horizontal sync pulse polarity
VTOT ? Returns the vertical total (in lines)
VRES ? Returns the vertical active (in lines)
VSPD ? Returns the vertical sync pulse delay (in lines)
VSPW ? Returns the vertical sync pulse width (in lines)
VSPP ? Returns the vertical sync pulse polarity
HVPD? Returns the pixel delay between the H and V sync pulses
