DC Power math channel
- Click on More in the left-hand tool panel to reveal the Math channels button
- Note: Clicking on the “Star” symbol to the left of the Math channels button will place the Math channels option in the left-hand tool panel where it will remain ready for use without having to select More
- Upon selecting Math channels, the math channel library will appear, click on the + symbol located at the foot of the Math channel list
- The math channel wizard will now open to reveal multiple options to create a math channel
- Click on Scientific functions, select DC Power and populate the formula field by choosing the relevant channel displaying Volts and the corresponding channel containing the desired Amperes
Below we have opted for A*B as voltage is present on channel A and the corresponding current on channel B
- Moving through the math channel wizard, give your math channel a name, color and complete the set-up by clicking on “Finish”
Below we have the completed DC power math channel displayed in the graph view
Feedback on the design and function of the DC Power math channel feature would be most welcome. Click on More > Help and support > Send Feedback within the software
Channel options panel now retains the same opened tab when switching between channels.
The neat feature titled above will enhance the user experience when configuring channel options manually. (Thanks to direct feedback from our customers)
- Below we have the Channel options Probe tab in view for Channel A where several probes can be selected
- Clicking on Channel B, C or D lozenge will no longer return the channel options panel to the Vertical tab (as with previous builds) but instead, remain open for probe selection
- The same applies to all Channel option tabs where the currently open tab remains visible regardless of the channel lozenge selected

RMS math channel for DC coupled signals
Thanks to the software development teams, this process has now been simplified given the arrival of the RMS math channel option
- Following the instructions described above for creating a DC Power math channel, open the math channel wizard
- Click on rms and select the channel to which the math channel is to be applied
- Below we have requested an RMS math channel be applied to channels B (PWM signal) and channel D (actuator current controlled by PWM signal)
Below we have applied both RMS math channels and their associated measurements
Note: RMS maths & measurements finds the RMS average of the whole signal exactly as displayed, including any AC or DC components. This would be proportional to the power dissipated in a resistive load connected to / controlled by such signals.
In contrast, RMS ripple subtracts any DC component and then calculates the RMS average of just the AC part of the signal (as if the DC component was not present) This is identical to selecting AC coupling and then applying RMS maths or measurements
Having the RMS & RMS ripple maths and measurement feature will provide the best of both worlds whereby you can still visualise the DC component of the signal (unlike AC coupling) whilst being able to derive the desired contents (e.g. AC ripple) within the signal using a combination of maths & measurements

Cycle time math channel
Continuing on the theme of math channels, there is now an easier route to graphing cycle times using the cycletime math channel
Below, we have once again utilised the math channel wizard to apply the cycle time math channel
Below we have applied the cycle time math channel and confirmed the results using Measurements

Filtering the Serial decoder or Deep Measure table will now update live
Below we will focus on the serial decoder table, however the same applies to Deep Measure.
- Below we have opened the PicoScope Guided Test for CAN bus serial decoding
- Note: The Pico serial decoder table is present as the Guided Test has applied a CAN bus decoder to the A-B math channel
- Clicking on the Filter icon will allow the user to apply a filter to the content of the decoder table
- Below we have opted to add a filter to the ID field that Contains the Argument 1F5
With the filter applied, the decoder table only contains IDs 1F5
- Clicking the filter summary dialog box will allow the user to edit the filter, whereby the decoder table will update live
- Below we have edited our ID value from 1F5 to 1F; note how the decoder table ID column has updated immediately to display all IDs containing 1F which includes, 1F0, 1F3 & 1F5
Note: The live updating of the serial decoder table only applies when editing a search field, not on the creation of a search field entry
