TMAU
Timing Measurement Analyzer Use
Class DVI signal analyzer
Description Initiates a measurement of the timing received from an external DVI source (via the DVI
Input connector). To do this, the PNSF command must be set to MEASURED. Measured
parameters are written into the format buffer.
Note: If PNSF is set to CURRENT, then the TMAU command leaves the parameters of the
currently selected format in the format buffer.
The timing parameters can be read back via queries using the following commands
Command syntax TMAU
SCAN ? Returns the scan type
PRAT? Returns the pixel rate (in Hz)
FRAT? Returns the frame 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.
