Operation Event Register (OEVR). This register has the same content as the Opera-
tion Condition Register.
Operation Condition Register (OCR). The Operation Condition Register is made up
of six bits, which note the occurrence of three different types of events as shown in
Figure 4-4.

Bit Function
15 to 9 ––––– Not used
8 WTRIG
CH2 Waiting for Trigger. Indicates whether the instrument is waiting for a
trigger. This bit is set when CH 2 (in the case of dual-channel model)
is waiting for a trigger. Bit is reset when the waiting-for-trigger status is
canceled.
5 WTRIG
CH1 Waiting for Trigger. Indicates whether the instrument is waiting for a
trigger. This bit is set when CH 1 (in the case of dual-channel model)
is waiting for a trigger. Bit is reset when the waiting-for-trigger status is
canceled.
4 ––––– Not used
3 SWE Sweep. Indicates whether the instrument is executing a frequency
sweep. This bit is set when a frequency sweep is being executed on
CH 1 or another channel (in the case of dual-channel model). Bit is
reset when the execution stops.
2 to 1 ––––– Not used
0 CAL Calibration. Indicates whether the instrument is being calibrated. This
bit is set when calibration is in progress and is reset when the
calibration is complete.
