Accurately capture waveforms with diverse parameters  
- Advanced trigger function -  
Trigger during capturing and search after capturing  
Set multiple triggers on a single channel  
The trigger function allows you to set diverse parameters to detect a  
particular waveform anomaly during capturing. Setting the pre-trigger  
mode allows you to monitor the pre-trigger waveform. This is useful  
for analyzing the cause of the anomaly.  
On the other hand, the search function allows you to detect an anom-  
aly after all data is captured. This allows you to search for and display  
an anomaly in the same manner as with the trigger function.  
When a waveform is unpredictable and setting a parameter during  
measurement is difficult, it is recommended to use the search function  
to locate an anomaly after capturing.  
Unlike with conventional MEMORY HiCORDERs, the 8860 series  
allows you to set multiple trigger parameters on a particular single  
channel. This allows you to set, for example, the glitch trigger, level  
trigger, window-out trigger, voltage drop trigger, window-in trigger,  
and on the same input waveform  
to monitor it. (8 parameters in  
the 8860-50 and 16 parameters  
in the 8861-50 can be set.)  
A simple level trigger causes the  
start trigger to be activated  
n Stop trigger for the MEM function  
Unlike with conventional MEMORY HiCORDERs, a stop trigger is supported. This  
enables the timing of measurement to be controlled for both the MEM and REC  
functions. This also allows you to set Start or Stop independently for each trigger  
source, thus enabling the timing of measurement to be controlled in a variety of  
combinations. (Start or Stop trigger can also be set to the logical source.)  
The eighth level trigger causes the  
stop trigger to be activated (in the  
case of specifying the event times)  
n Capture a sudden power loss with the drop trigger  
Set the voltage drop trigger to capture a sudden power loss resulting from a blackout  
caused by lighting or a circuit breaker tripping.  
Set the window out trigger to capture an impulse noise or surge noise (voltage swell)  
caused by, for example, the solenoid opening and closing.  
n Slope trigger  
Unlike with conventional MEMORY  
HiCORDERs, a slope trigger is supported.  
This allows you to monitor a noise  
superimposed on periodic waveforms such  
as a power waveform. This also allows you  
to monitor a rapid change in temperature  
Power waveform noise  
Power waveform noise  
Rapid change in temperature  
with the amount of change in slope instead  
of level.  
For edge detection of pattern “1, 0, 0, ,” the  
trigger is not activated in this position.  
For edge detection, the trigger is not activated unless  
the condition is not met after the start of measurement  
n Edge detection and level detection of the logic trigger  
Unlike with conventional MEMORY HiCORDERs supporting only  
edge detection, the Models 8860-50 and 8861-50 supports level  
detection of the logic trigger. This function causes the trigger to be  
activated when a specified pattern occurs, even if the logic pattern  
condition is not met after the start of measurement.  
For level detection, the trigger is activated only if the  
condition is met after the start of measurement
