Agilent 54622D remote trigger problem

Hi All,

First post here !
I currently am having problems with the 54622D scope when i set to SINGle mode remotely and then wait for a trigger.
I am using the latest firmware (A2.31) and am remotely controlling via labview 7.1.

Essentially I set  the scope to trigger on Chan1 positive edge Single Trigger.
I then read the TER register bit in a loop as recommended in the help file until a trigger occurs.
The TER bit should change to 1 when a trigger occured and reset to 0 when it is read.

The problem I am having is that the scope sets correctly to SING but the TER bit gets set to 1 even though I can see the scope has not triggered. The light behind the SINGLE button is still active. I have tried clearing the Read queue before setting the SINGle mode and this reads as 0 so the scope is setup correctly.

Is there a bug in the firmware or am I missing something regarding Single mode ?
