4 Triggering the Oscilloscope

You can set the oscilloscope to trigger during a high chip select (CS), a low chip select (~CS), or after a Timeout period during which the clock signal has been idle.

•If the framing signal is set to CS (or ~CS), the first clock edge as defined, rising or falling, seen after the CS (or ~CS) signal transitions from low to high (or high to low) is the first clock in the serial stream.

Chip Select — Press the CS or ~CS softkey or turn the Entry knob to select the channel that is connected to the SPI frame line. The label (~CS or CS) for the source channel is automatically set. The data pattern and the clock transition must occur during the time when the framing signal is valid. The framing signal must be valid for the entire data pattern.

As you press the CS or ~CS softkey (or rotate the Entry knob on mixed-signal oscilloscopes), the CS or ~CS label for the source channel is automatically set and the channel you select is shown in the upper-right corner of the display next to “SPI”. When you press the Frame by softkey, the graphic shown on the previous page changes to show timeout selection or the current state of the chip select signal.

Adjust the trigger level for the selected analog channel by turning the Trigger Level knob. Press the D15 Thru D0 key and select Thresholds to set the threshold level for digital channels. The value of the trigger level or digital threshold is displayed in the upper-right corner of the display.

•If the framing signal is set to Timeout, the oscilloscope generates it’s own internal framing signal after it sees inactivity on the serial clock line.

Clock Timeout — Select Clock Timeout in the Frame by softkey, then select the Timeout softkey and turn the Entry knob to set the minimum time that the Clock signal must be idle (not transitioning) before the oscilloscope will search for the Data pattern on which to trigger. When you press the Frame by softkey, the graphic shown on the previous page changes to show timeout selection or the current state of the chip select signal.
