When you start Wavy, a main window comprising [Graph] and [Worksheet] windows appears. In the [Graph] window, you can set the steps by drawing lines with a mouse. In the [Worksheet] window, you can set the steps by entering the values.
ience Execution window
This window is used to execute sequences. You can display three types of graphs using the tabs.
A sequence is a feature that automatically executes the predefined steps in a given order. You can simulate various waveforms. A sequence comprises multiple steps, which will be executed in a given order. A single sequence can comprise up to 1024 steps. The execution of the last step normally concludes the sequence. If you set the repetition count of a sequence, however, the sequence will be repeatedly executed until it reaches to the last count.

NOTE The maximum value that can be specified on Wavy is limited to 105 % of the rated output of the PMX series specified by [Instrument] in the interface window. For example, if you specify PMX35-1A, you will not be able to set values exceeding 36.75 V (35 x 1.05). For a sequence, you need to set the following conditions common for all steps.
Operating mode (Constant Voltage (CV) or Constant Current (CC)) Set the operating mode. The current/voltage limit can also be specified. Protection settings Configure the protection settings. Repetition count Set how many times to repeat the sequence. Step interval Configure the step interval unit. For each step, you need to configure a set of values as shown in the figure below. One step corresponds to one operation in a waveform to be executed.
Time [s] indicates the accumulated time from the beginning, which is unable to be modified. . Voltage (in CV mode) Set the voltage when Constant Voltage (CV) mode being enabled. Current (in CC mode) . Set the current when Constant Current (CC) mode being enabled. Interval Set the execution time for the step. . Transition (Step or Ramp) Set the transition type for the step. The resolution of ramp transition is 50 ms to 100 ms. When the step interval is limited, the ramp line may not be linear. . Output (on or off) Switch on/off of the output. You can edit the steps by either drawing lines in [Graph] window or entering values in [Worksheet] window.

Displaying the monitor graph
To display the real-time monitor graph, select the [Display the monitor graph] check box under [Select Items to be Monitored]. Further, additional tabs — [Monitor Graph] and [Setting/Monitor Graph] — are displayed in the [Run] window. On the [Setting/Monitor Graph] tab, both setting graph and real-time monitor graph are displayed. You can set which graphs (current, voltage, and power) are displayed on the real-time monitor graph by clicking [Sequence] and then [Monitor Setup], and using [Select Items to be Monitored]. If you move the pointer over the graph, the monitored value will be displayed. p. 36
You can change the scale on X-axis and Y-axis in the real-time monitor graph. To change the scale, right-click on the real-time monitor graph and select [Scale] from the context menu. The [Scale] window opens. If you select the [Maximum time], [Maximum current], [Maximum voltage], or [Minimum Value] check box, the auto scaling function is enabled. While the auto scaling function being enabled, the scale is  automatically adjusted according to the monitored values. When the auto scaling function is disabled, the monitored value beyond the range does not appear in the graph.
When the maximum time is set to be automatically scaled
When the [Auto] check box of [Max time] is selected, you can specify either [Roll mode] or [Normal mode].
■ Roll mode
The X-axis and Y-axis are simultaneously scaled. The display range is defined by subtracting the minimum time setting from the maximum time setting.
■ Normal mode
In normal mode, the minimum time is fixed to a given value whereas the maximum time is scaled. When the [Scrolling within the specified range] check box is selected, the graph is scaled when the monitored value exceeds the maximum time on the X-axis. In this case, the time range to be scrolled is defined by subtracting the minimum time setting and the scrolling time from the maximum time setting. For example, if the minimum time is set to 0 s, the maximum time is set to 23 s, and the scroll time is set to 10 seconds, the time range will be 13 s (calculated from 23-0-10).
You can set the interval for monitoring. To change the monitoring interval, click on the [Sequence] menu and select [Monitoring Setup], or on the toolbar. The [Monitoring Setup] window opens. click Under [Select Items to be Monitored], set the [Monitoring Interval] to a value between 200 ms and 60000 ms.
You can save the monitored data in a text format. To save the monitored data, click on the [Sequence] menu and select the [Monitoring Setup], or n the toolbar. The [Monitoring Setup] window opens. Select [Yes] under the [Save File], and specify the destination to save the file. The given file name concatenates the operating mode, the starting date and time of the execution, and the file extension. You can change the file extension (.txt by default). You can set the unit of elapsed time to be written to the file. The accuracy of the elapsed time depends on your PC environment. [s]: Seconds [h:min:s]: Hours, minutes, seconds If you select the [Data right before Run] check box under [for Saved Data], "0 s" will be written to the beginning of the saved data file ("0 s" would be regarded as the value monitored prior to the sequence execution). If the [Data Immediately after End/Stop] check box is selected, the monitored values after the sequence is completed or aborted will be appended to the saved data. Under [Order for output to file], you can set the order in which the monitored data (time, voltage, and current) is written to the file.

The maximum values that you can enter are limited to the rated output of the connected PMX series x 105 %.
■   Voltage Setting and Current Setting
Enter a value in [Voltage] and click [Set]. Likewise, enter a value in [Current] and click [Set]. These settings are transmitted to the PMX Series. The up and down arrow keys to the right of the numeric boxes change the values in 1 V or 1 A steps. If you enter a value in [Step] under [Step Setting], you can adjust the voltage and current by clicking [Up] or [Down].
■ Output
Click [ON] to turn on the output. Click [OFF] to turn off the output. The present status of the PMX Series will be displayed in the indicator above those buttons.
■ Alarm Clear
Click [Clear] to clear the alarm that occurred.
■ Result
The response from the target PMX series is displayed.
■ Monitor
Click (Run) to start monitoring. Click [Stop] to stop monitoring. The elapsed time is indicated during monitoring. When monitoring is in progress, Wavy also monitors the activation of the PMX series’ protection functions. When a protection function is activated, the status appears next to [Status]. The acti- vation of protection functions is not monitored when monitoring is not in progress. While the monitoring being stopped, you can set the monitor interval. To save the monitored output data to a file, select [Save File] check box under [Setting]. To spec- ify the file destination and the unit of the elapsed time written to the file, click [Folder] under [Setting]. The accuracy of the elapsed time varies depending on your PC environment.
[s]: Seconds
[h:min:s]: Hours, minutes, seconds The file name concatenates the operating mode, the start date and time of the execution, and the file name extension. You can change the file extension (.txt by default).
You can transmit the commands to the PMX Series directly from Wavy for PMX. Click on the [Tool] menu and select (Command Control). The [Command Control] window opens. Enter a command and click [Run]. Then, the result will be displayed. The transmitted commands (successfully transmitted and received commands only) appear as list items in the drop-down menu. To clear the list items, click [Clear]. For details about the commands, see the PMX Series Communication Interface Manual.
The PMX Series functions as a constant-voltage source or a constant-current source. In constant- voltage (CV) mode, the PMX Series holds the output voltage to a certain value regardless of the load change. Whereas in constant-current (CC) mode, the PMX Series holds the output current to a certain value regardless of the load change. These operating modes are determined by the follow- ing three factors. Output voltage setting (Vs) Output current setting (ls) Load resistance (RL) The figure below explains the operating modes. The load resistance is denoted as "Rι: The resistance, which is calculated from the voltage and cur- rent settings (RC=Vs/ls), is denoted as "Rc". The PMX Series is designed to function in CV mode within A range, and function in CC mode within B range. A and B are divided by the "RL=Rc" bound- ary line. On this boundary line, the output voltage equals the voltage setting, and the output cur- rent equals the current setting. When the load resistance Rι is greater than the resistance Rc, the PMX Series operates in CV mode as the operating point (p point) lies within A range. In this case, the current setting (ls) equals the current limit. While the PMX Series is operating in CV mode, the output voltage is hold to a certain level. Output current "l", on the other hand, is determined by the equation l=Vs/RL and is lower than the current limit "Is". The flowing current may not equal the current setting. For the loads in which transient peak current flows, the current limit "Is" needs to be set higher than the peak value. In contrast, when the load resistance R L is lower than the resistance Rc, the PMX Series operates in CC mode as the operating point (q point) lies within B range. In this case, the voltage setting (Vs) equals the voltage limit. While the PMX Series is operating in CC mode, the output current is hold to a certain level. Output voltage “V”, on the other hand, is determined by the equation V=Is/RL and is lower than the current limit "Vs". The flowing voltage may not equal the voltage setting. For the loads which causes the transient voltage surge, the voltage limit "Vs" needs to be set higher than the voltage surge.
Crossover point
The operating modes (CV or CC) automatically switches due to the changes in the load. A crossover point is referred to as the point where the operating mode switches. For example, if the load changes and the output current reaches to its limit while in CV mode, the PMX Series switches to operate in CC mode for protecting the load. Likewise, if the output voltage reaches its limit while in CC mode, the PMX Series switches to operate in CV mode.
CV/CC modes operation example
The following cases take the PMX Series with rated output voltage 100 V and rated output current 10 A as examples. First, assume that 8 Ω load resistance ( L ) is connected to the output terminals of the PMX Series, and the output voltage and output current are set to 30 V and 5 A respectively. In this case, the PMX Series operates in CV mode because RL (8 Ω) is greater than Rc (Rc=30 V/5 A=6 Ω). You can still raise the voltage up to 40 V (calculated from Vs = ls x R L , that is, Vs = 5 A x 8 Ω = 40 V) in CV mode. If you attempt to raise the voltage any further, however, the voltage reaches to the crossover point and the PMX Series automatically switches to operate in CC mode. To allow the PMX Series to continue operating in CV mode, raise the current limit. Next, assume that 5 Ω load resistance (Rι) is connected to the output terminals of the PMX Series, and the output voltage and output current are set to 30 V and 5 A respectively. In this case, the PMX Series operates in CC mode because RL (5 Ω) is lower than Rc (Rc=30 V/5 A=6 Ω). You can still raise the current up to 6 A (calculated from Is=Vs/Rι, that is, Is=30 V/5 Ω=6 A) in CC mode. If you attempt to raise the current any further, however, the current reaches to the crossover point and the PMX Series automatically switches to operate in CV mode. To allow the PMX Series to continue operating in CC mode, raise the voltage limit.
