SPI bus trigger polarity
The SS, MISO, and MOSI Active controls allow you to select when the enable is active.
Select (H) High or (L) Low from the drop-down menu.
The SCLK Active control provides compensation for inverted signals or synchronization on the falling
edge of the clock.
Select Rising or Falling from the drop-down menu.

Supported ADEs
TekVISA supports these Application Development Environments:
Microsoft C/C++
Microsoft Visual Basic
LabVIEW graphics software using the G language
MATLAB analysis software
TekProbe/TekVPI interfaces
These interfaces enable the instrument to sense information about the probe such as the serial number and
other unique identification information. It also allows the instrument to provide power directly to the probe.
With this information, the instrument can automatically set up its requirements to match the characteristics
of the probe, such as termination and attenuation.
