Parameters
Command Example
FRAT?
Queries the frame rate
of the outgoing HDMI
format.
FRAT?
Not Applicable
To read the frame rate of the
outgoing HDMI signal:
FRAT?
+60.000E+00
HDCP?
Runs an HDCP
authentication test on
an HDMI sink device
HDCP? <frames>
Number of frames:
Where frames is number of
frames rounded to the nearest
128 frames.
Results:
where results are:
0 = pass
1 = fail
To run an HDCP authentication
test on an HDMI sink device or
repeater device:
To run an HDCP test for 128
frames: (pass reported)
HDCP? 255
To run an HDCP test for 256
frames:
HDCP? 257
0
To run an HDCP test for 512
frames (with a failure reported):
HDCP?
1
HPAG?
Query the incoming
sink for hot plug pin
status.
HPAG?
<hotplug>
Where hotplug can be 0 (no hot
plug detected) or 1 (hot plug
deteted)
To check for hot plug on the
HDMI Out port:
HPAG?
HRAT
Sets the horizontal
rate of the video
timing.
HRAT <rate>
HRAT?
<rate>
Where rate can be within the
range of:
1000Hz to 130000Hz
To set the horizontal rate to
15000Hz:
HRAT 15000
ALLU or FMTU
HRES
