How Much Lag Time is There When Inputting or Outting a Signal from the EXT Terminal of the WE7000 Measurement Station?
The lag time from the external terminal to the bus trigger / time base is as follows:
When inputting from TRIG IN:
TRIG IN -> bus trigger signal : 40 ns (typical value)
TRIG IN -> time base signal : 25 ns (typical value)
When inputting from EXT. I/O:
EXT. I/O -> bus trigger signal : 25 ns (typical value)
EXT. I/O ->time base signal : 10ns (typical value)
When outputting to EXT. I/O:
EXT. I/O <- bus trigger signal : 25ns (typical value)
EXT. I/O <- time base signal : 25ns (typical value)
The lag time between the bus trigger / time base and each measurement module differs depending on the module. See the following example:
Bus trigger signal -> WE7111 Digital oscilloscope module : 30 ns
+ sampling interval (typical value*)
* Typical value represents a typical or average value. It is not strictly guaranteed.
