Data Pattern
You can use a data pattern as a search condition. The data pattern search condition is
met when the specified pattern matches the sampled data source pattern.
• Y
ou can set a pattern consisting of up to 128 bits. Set the pattern in hexadecimal or
binary notation.
• If you specify X, the condition is assumed to be met regardles
s of the corresponding
bit status.
• If a binary pattern contains any Xs, the corresponding hexade
cimal display will be “$.”
Bit Rate
If the clock is set to OFF, the DL9000 samples the data source at the specified bit rate.
Selectable range: 1 bps to 1 Gbps
CS
If the clock is set to ON, the period that the DL9000 tests the data source can be
controlled using the CS state condition.
ON Tests the data source while the state condition is met.
OFF Tests the data source at all times.
• State Condition
Set each signal state to H, L, or X. The state condition is true when the selected state
and the input signal state meet the following condition.
H When the signal is high
L When the signal is low
X Not used as a search condition (Don’t care)
* The level for determining high or low is the level that you set below when you set the signal to
a channel from CH1 to CH4 or from M1 to M4.
• Logic
You can select the state condition logic. The state condition is true when the logic
condition is met.
AND When the state of all signals matches
OR When the state of any signal matches
Latch
If the clock is set to ON, you can specify the timing when the sampled data source
pattern is compared with the specified pattern. If the source is set to X, comparison is
made on each clock.
You can select the latch source edge that specifies when the data patterns are compared.
On the rising edge
On the falling edge
