Triggering on Waveforms
About this Chapter
This chapter provides an introduction to t he t r igger functions of the test t ool. Tr igger ing tells the t est tool when to begin displaying the waveform. You can use fully automatic triggering, t ake cont r ol of one or m or e main trigger functions (sem i- aut om at ic t r iggering) , or you can use dedicated trigger functions to capt ur e special waveforms.
Following are some typical trigger applications:
Use the Connect-and-View™ function to have full
automatic triggering and instant display of virt ually any waveform.
If the signal is unstable or has a very low frequency,
you can control the trigger level, slope, and t r igger delay for a better view of the signal. ( See next section.)
For dedicated applications, use one of the four
manual trigger functions:
Edge triggering
External triggering
Video triggering
Pulse Width triggering

Setting Trigger Level and Slope
The Connect-and-View™ function enables hands-off triggering to display complex unknown signals.
When your test tool is in manual range, do t he following:
Perform an auto set . AUTO appears at the top right of t he scr een.
Automatic triggering assures a stable display of virtually any signal.
From this point, you can take over t he basic t r igger controls such as level, slope and delay. To optimize trigger level and slope manually, do the following:
Figure 26. Screen with all Tri gger I nf or m ation
1 Display the TRIGGER key labels.
2 Trigger on either positive slope or
negative slope of the chosen waveform.
3 Enable the arrow keys for manual
trigger level adjustment.

4 Adjust the trigger level.
Observe the trigger icon that indicates the trigger position, trigger level, and slope.
At the bottom of t he scr een t he trigger parameters ar e displayed. (See Figure 26.) For example, means that input A is used as the tr igger sour ce with a positive slope.
When no trigger is found, t he t r igger par ameters appear in gray.
Using Trigger Delay or Pre-trigger
You can begin to display the waveform some time befor e or after the t r igger point has been det ected. Initially, you have 2 divisions of pre-trigger view (negative delay).
To set the trigger delay, do t he f ollowing:
5 Hold down to adjust the trigger
delay.

Using the Independently Floating Isolated Inputs
You can use the independently floating isolated inputs to measure signals that are independently floating f r om each other.
Independently floating isolated inputs offer additional safety and measur em ent c apabilit ies com pared to inputs with common references or gr ounds.
Measuring Using In dependen t ly Floating Isolated Inputs
The test tool has independently floating isolated inputs. Each input section (A, B, External Trigger / DMM ) has it s own signal input and its own reference input. The reference input of each input sect ion is electrically isolated from the ref er ence input s of t he ot her input sections. The isolated input architecture m akes t he t est tool about as versatile as having three independent instruments. The advantages of having independently floating isolated inputs are:
It allows simultaneous measurement of
independently floating signals.
Additional safety. Since the commons are not direct ly
connected, the chance of causing short cir cuit when measuring multiple signals is greatly reduced.
Additional safety. When measuring in systems with
multiple grounds, the ground curr ent s induced are kept to a minimum.
Because the references are not connected together inside the test tool, each refer ence of the used inputs must be connected to a ref er ence voltage.
Independently floating isolated inputs are still coupled by parasitic capacitance. This can occur between the input references and the environment , and between the input references mutually (see Figure 44) . For this reason, you should connect the references to a syst em gr ound or another stable voltage. If t he reference of an input is connected to a high speed and / or high voltage signal, you should be aware of parasitic capacitance. (See Figures 45, 46, 47 and 48.)

Tips
Saving Battery Life
7
Saving Battery Life
When operated on the batt er y ( no battery charger connected), the test t ool conserves power by shut t ing itself down. If you have not pressed a key f or at least 30 minutes, the test tool turns itself off autom atically.
Note
If the power adapter is connected, there is no automatic power shutdown.
Automatic power shutdown will not occur if TrendPlot or Scope Record is on, but the backlight will dim. Recording will continue even if the battery is low, and retention of memories is not jeopardized.
Setting the Power Down Timer
Initially the power shutdown time is 30 minutes. You can set the power shutdown time to 5 m inut es as f ollowing:
1 Display the USER key labels.
2 Open the User Opti ons m enu.
3 Open the Battery Save O pt i ons
menu.
4 Select 5 M inutes.

Changing the Auto Set Options
With the next procedure you can choose how auto set behaves when you press the
AUTO (auto set) key.
4 Select Signal > 1 Hz, then jump
to Coupling.
1 Display the USER key labels.
2 Open the User Opti ons m enu.
3 Open the Auto Set Adjust
menu.
If the frequency r ange is set t o > 15 Hz, t he Connect - and­View function responds more quickly. The response is quicker because the test tool is instructed not t o analyze low frequency signal components. However, when you measure frequencies lower than 15 Hz, the t est tool must be instructed to analyze low frequency components for automatic triggering:
74
With the coupling option you can choose how auto set behaves. When you press the
AUTO (auto set) key, t he
coupling can either be set to dc or left unchanged:
5 Select Unchanged.
Note
The auto set option for t he signal frequency is similar to the automatic t r igger option for the signal frequency. (See Chapter 5: “Aut om at ic Trigger Options”). However, t he aut o set option determines the behavior of t he aut o set function and shows only effect when you press the auto set key.

Extending Battery Operation Time
Typically, NiMH batteries always meet the specified operating time. However, if t he bat t er ies have been extremely discharged (for exam ple, when empt y bat teries were stored for a long period) it is possible that the battery condition has deteriorated.
To keep the batteries in optimal condition, observe t he following guidelines:
Operate the test tool on batteries until the
symbol appears at the bottom of the screen. This indicates that the batter y level is low and that the NiMH batteries need to be recharged.
To obtain optimal battery condition again, you can
refresh the batteries. During a battery ref r esh, t he batteries will be fully discharged and charged again. A complete refresh cycle takes about 12 hours and should be done about four times a year. You can check the latest battery r ef r esh dat e. See sect ion “Displaying Calibration Information”.
To refresh the battery, make sure that the test tool is line powered and proceed as follows:
1 Display the USER key labels.
2 Open the User Opti ons m enu.
A message appears asking whether you want to start t he refresh cycle now.
3 Start the refr esh cycle.
Do not disconnect the batt er y char ger dur i ng t he refresh cycle. Thi s w ill interrupt the refresh cycle.
