Sequence Event Register:
Bit B0  Not used.
Bit B1, Layer 1 (Lay1)  Set bit indicates that instrument operation is in arm layer 1 (PTR), or
that operation has exited from arm layer 1 NTR).
Bit B2, Layer 2 (Lay2)  Set bit indicates that instrument operation is in arm layer 2 (PTR), or
that operation has exited from arm layer 2 NTR).
Bits B3 through B15  Not used.
Programming example 10 OUTPUT 716; “:stat:meas?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Queries the Measure Event Register.
