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 ref erence waveform as the Slave Select source.

REF<x> _D<x> speciﬁes a digital reference waveform as the clock source

waveform for the speciﬁed 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

speciﬁed bus. The bus is speciﬁed by x.

Conditions

Requires option SR-EMBD.

Group

Bus

Syntax

BUS:B<x>:SPI:SELect:THRes hold <NR3>

BUS:B<x>:SPI:SELect:THRes hold?

Arguments

<NR3> is the SPI Select (SS) source threshold for the speciﬁed 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.
