4.5 Buffer Mode
Buffer simulation is the mode to send data of the TXD or RXD side recorded in the capture buffer. Therefore, it can
reproduce the communication of data monitored.
Preparation
Press [MENU] and touch “Operation mode: Simulation”->“ Function ": BUFFER”.
Touch “Advanced settings”.

Repeated transmission Appointing repetitive transmission ON( ) / OFF( )
IDLE TM Space time between frames 0~99999 1msec. unit
Select the recording area from “BUF1” or “BUF2” which is the
half of capture memory.
Monitor communication data and perform a reproducing test in
the Buffer mode.
Monitor data and save data in the “BUF1” (or “BUF2”).
To prevent data from overwriting, mark on the box of “Protection”.
Change the recording area to another half of buffer, “BUF2” (or “BUF1”).
2.5 Communication Condition
2.6 Record Control (Dividing a Capture Buffer)
Buffer simulation is not going to start if it selects “BUF0”.
Set the flowing items below.
To send data in the TXD, select DTE mode. To send data in the RXD, select DCE mode. Set the conditions of
analyzer as same as the condition of monitored data.
2.3 Measurement Port
2.5 Communication Condition
If the condition of analyzer is not same as the condition of monitored data, the result of this testing may not be accu-
rate.
