:COMPliance Commands
:COMPliance:USB:TEST
(see
page 1208
)
Command Syntax
:COMPliance:USB:TEST <test>
<test> ::= {DHSS | HHSS | DLSS | HLSS | DFSS | HFSS}
The :COMPliance:USB:TEST command selects the type of signal quality test
to perform:
•
DHSS — Device Hi- Speed Signal Quality.
•
HHSS — Host Hi- Speed Signal Quality.
•
DLSS — Device Low Speed Signal Quality.
•
HLSS — Host Low Speed Signal Quality.
•
DFSS — Device Full Speed Signal Quality.
•
HFSS — Host Full Speed Signal Quality.
For Hub upstream testing, select the Device tests.
For Hub downstream testing, select the Host tests.
Low and Full Speed tests require two or three single- ended probes.
Hi- Speed tests are available only on 1.5 GHz bandwidth oscilloscopes, and
a differential probe or SMA cable connections are required.
Note that the N2750A Series InfiniiMode differential probes cannot be
used with the Hi- Speed Signal Quality test fixtures because they have
damping resistors and the USB test fixture also has damping resistors
specifically designed for the E2678A socketed probe heads.
Query Syntax
:COMPliance:USB:TEST?
The :COMPliance:USB:TEST? query returns the selected signal quality test
type.
Return Format
<test><NL>
<test> ::= {DHSS | HHSS | DLSS | HLSS | DFSS | HFSS}
