Table 12-1: List of Commands (alphabetical) – For Testing HDMI Sink Devices
Enables you to send
specific parameter
values of the Source
Product Descriptor
infoframe out the
HDMI output
independent of the
HDMI stream.
XSPD:spdparameter <value>
Where spdparameter is one of the values identified
below and value is an allowed value associated with
the parameter provided in CEA-861-E.
XSPD [VNS [PDS [SDI]]
Where:
XSPD – Vendor string name.
PDS – Product description string.
SDI – Source device information (see EIA/CEA-861-
E standard)
To assign a vendor string name:
XSPD QDI HDMI-Analyzer
IFGU
To query the vendor string
name:
XSPD?

Table 12-2 below provides the list of commands supported or testing HDMI sink devices:
Note: The commands are not case sensitive.
Table 12-2: List of Commands (alphabetical) – For Testing HDMI Audio in Sink Devices
Sets the audio rate on
Optical, SPDIF and
HDMI LPCM audio.
Where rate is one of:
32000, 44100, 48000, 88200,
96000, 176400, 192000.
To set the audio sampling rate to
48kHz:
ARAT 48000
FMTU
Sets the amplitude on
either a specific
channel or channels.
SAMP <amp> <ch>
SAMP?
<amp> <ch>
Where amp is between the
range of:
min = -99 dB
max = 0 dB
Where ch is in one of:
0 - 7
To set the amplitude of the audio
signal on channel 1 (FR) to
-3dB:
SAMP -3 1
FMTU
To set the amplitude of the audio
signal on all channels to -6dB:
SAMP -6
FMTU
Sets the sine wave
frequency on either a
specific channel or all
channels.
SRAT <rate> <ch>
SRAT?
<rate> <ch>
Where rate is between the
range of:
min = 8Hz
max = 20000Hz
Where ch is in one of:
0 - 7
To set the sinewave frequency
of the audio signal on channel 1
(FL) to 2000 Hz:
SRAT 2000 0
FMTU
To set the sinewave frequency
of the audio signal on all
channels to 4000Hz:
SRAT 4000
FMTU
