Latch (Latch)
You can specify the timing at which the data source pattern sampled in sync with the clock source is compared
with the specified pattern.
Latch Source (Source)
Set latch source to one of the settings below. The available settings vary depending on the model.
CH1 to CH4, None (Latch is not used. Comparison is made for each clock.)
Polarity (Polarity)
You can select which latch source edge causes the data patterns to be compared.
On the rising edge
On the falling edge
You cannot set enable or latch on the 2-channel model.
Trigger Condition (Condition Setup)
You can use data patterns as trigger conditions. The data pattern trigger condition is met when the sampled data
source pattern matches the specified pattern.
Data Length (Data Size)
Set the data pattern bit length.
Selectable range: 1 to 128 bits
Data Pattern (Hex/Bin)
Set the data pattern for the specified data size in hexadecimal (Hex) or binary (Bin) notation.
If you specify X in the pattern, the condition is assumed to be met regardless of the corresponding bit status.
If a binary pattern contains any Xs, the corresponding hexadecimal display will be “$.”
Bit Rate (Bit Rate)
If the clock is set to OFF, the instrument samples the data source at the specified bit rate.
Selectable range: 1 kbps to 50 Mbps (in 1 kbps steps)
Level (Level), HF Rejection (HF Rejection)
Set these items for data, clock, enable, and latch.
These items are the same as those of the edge trigger.
Hysteresis (Hysteresis)
This item is the same as that of the CAN bus trigger.
