Group Bus
Syntax
BUS:B<x>:SPI:DATa:SOUrce
{CH<x>|CH<x>_D<x>|MATH<x>|REF<x>|REF<x>_D<x>}
BUS:B<x>:SPI:DATa:SOUrce?
Arguments
CH<x>
designates an analog channel as the data source for the speci fi ed SPI bus.
CH<x>_D<x>
designates an digital channel as the bus SPI clock source.
MATH<x>
designates a math waveform as the data source.
REF<x>
designates a reference waveform as the data source.
REF<x> _D<x>
speci fi es a digital reference waveform as the data source
waveform for the speci fi ed SPI bus.
Examples
BUS:B1:SPI:DATA:SOURCE CH2
sets the SPI data source for the bus B1 to CH2.
BUS:B1:SPI:DATA:SOURCE?
might return
:BUS:B1:SPI:DATA:SOURCE CH3
,
indicating that the SPI data source for the bus B1 is set to CH3.
BUS:B<x>:SPI:DATa:THReshold
This command sets or queries the SPI Data (SDA) source threshold for the
speci
fi ed bus. The bus is speci fi ed by x.
Conditions Requires option SR-EMBD.
Group Bus
Syntax
BUS:B<x>:SPI:DATa:THReshold <NR3>
BUS:B<x>:SPI:DATa:THReshold?
Arguments
<NR3>
is the SPI Data (SDA) source threshold for the speci fi ed bus.
