BUS:B<x>:SPI:SELect:SOUrce?
Related Commands
BUS:B<x>:SPI:SELect:POLarity
Arguments
CH<x>
designates an analog channel as the buses' SPI Slave Select source.
CH<x>_D<x>
designates a digital channel as the buses' SPI Slave Select source.
MATH<x>
designates a math waveform as the Slave Select source.
REF<x>
designates a reference waveform as the Slave Select source.
REF<x> _D<x>
speci fi es a digital reference waveform as the clock source
waveform for the speci fi ed SPI bus.
Examples
BUS:B1:SPI:SELECT:SOURCE MATH3
sets the SPI Slave Select source for
the bus B1 to MATH3.
BUS:B1:SPI:SELECT:SOURCE?
might return
:BUS:B1:SPI:SELECT:SOURCE
CH3
, indicating that the SPI Slave Select source for the bus B1 is set to CH3.
BUS:B<x>:SPI:SELect:THReshold
This command sets or queries the SPI Select (SS) 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:SELect:THReshold <NR3>
BUS:B<x>:SPI:SELect:THReshold?
Arguments
<NR3>
is the SPI Select (SS) source threshold for the speci fi ed bus.
Examples
BUS:B1:SPI:SELect:THReshold 50.0e-3 sets the threshold to 50.0 mV.
BUS:B1:SPI:SELect:THReshold? might return
:BUS:B1:SPI:SELECT:THRESHOLD 0.0E+0 indicating the threshold is set to
0.0 V.
