Remote command:
BUS<m>:
RFFE:VERSion
on page 2060
Read mode
Selects, if the standard or synchronous read ("sRead") mode is used.
Remote command:
BUS<m>:RFFE:RDMD on page 2059
SCLK Source
Sets the source of the clock line.
Usually, the source is one of the analog channels. Reference and math waveforms are
available as source if the trigger source is one of the analog channels but not the serial
bus.
Alternatively, digital channels can be used if MSO option R&S RTO6-B1 is installed.
Digital and analog channels cannot be used at the same time.
For triggering on a serial bus, analog or digital channel sources are required.
Remote command:
BUS<m>:RFFE:CLOCk:SOURce on page 2055
SDATA Source
Sets the source of the data line.
Usually, the source is one of the analog channels. Reference and math waveforms are
available as source if the trigger source is one of the analog channels but not the serial
bus.
Alternatively, digital channels can be used if MSO option R&S RTO6-B1 is installed.
Digital and analog channels cannot be used at the same time.
For triggering on a serial bus, analog or digital channel sources are required.
Remote command:
BUS<m>:RFFE:DATA:SOURce on page 2056
Thresholds
Set the threshold values for digitization of signals for each line: the positive going
threshold (V
TP
, upper value), the negative going threshold (V
TN
, lower value), and the
hysteresis. The hysteresis is the difference of V
TP
and V
TN
.
If the signal value on the line is higher than the positive going threshold, the signal
state is high. Otherwise, the signal state is considered low if the signal value is below
the negative going threshold.
There are several ways to set the thresholds
"Threshold"
Enter the value directly in the field.
"Find thresh-
olds"
Executes the measurement of reference levels and sets the thresh-
olds to the middle reference level of the measured amplitude.
