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
8WTRIG
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.
5WTRIG
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.
