:OUTPut:AUDio:EAUDio?
Returns the current state of the embedded audio.
:OUTPut:AUDio:SIGNal <channel, frequency, amplitude>
Controls three Menu commands: channel selection, frequency, and
audio level. The channels are 1, 2, 3, 4, or ALL. The frequency
choices are 800HZ, 1000HZ, or SILENCE. The audio level can
range from –20 dBFS to –10 dBFS in 2 dBFS intervals. (Enter the
level as –10DBFS, –12DBFS, –14DBFS, –16DBFS, –18DBFS, or
–20DBFS.)
:
OUTPut:AUDio:SIGNal?
Returns the channel, frequency, and amplitude of the audio signal.
:OUTPut:AUDio:TIMing PAUDTIM | NAUDTIM1 | NAUDTIM2 |
NAUDTIM3 | NAUDTIM4 | NAUDTIM5
:OUTPut:AUDio:TIMing?
:OUTPut:AUDio?
Returns the signals and amplitudes for all four audio channels.
:OUTPut:BARS
:OUTPut:BARS:FIELd <numeric value>
Sets the field timing offset of the Serial Bars signal relative to the
genlock signal. This command can range from 2 fields advance to 2
fields delay. Enter the numeric value as 2, 1, 0, –2, or –1.
:OUTPut:BARS:FIELd?
Returns the current field timing of the bars signal relative to the
genlock signal as a string, where the value is absolute and advance
or delay is stated in the following text. For instance, setting to –2
will return
“2 Fields of Advance.”
.
:OUTPut:BARS:HCOarse <numeric_value>
Sets the coarse horizontal timing relative to the genlock signal. The
timing resolution is clock-cycles. The range is
"
32
m
sec. Positive
numbers set delay and negative numbers set advance.
NOTE
. The numeric value for this command is expressed in clock-cycles, not
microseconds. There is a conversion factor dependent upon the video standard in
use.
