- Use of the TAP1500L filter requires a scope model capable of creating a MATH channel and applying an arbitrary filter to a selected input. 
- The following steps assumes that the TAP1500L filter is on the C:\ drive of the target scope and the probe is connected to channel 1 of the scope.  If the filter is in a different directory location, or the probe is connected to a different channel of the scope, make appropriate adjustments in the setup.

1. Press the "Default Setup" button on the scope front panel. If you are setting up multiple TAP1500L probes with the filter, this step only needs to be done once.
2. Connect the TAP1500L to the scope.
3. On the scope display, tap the "Add New Math" button.
4. On the bottom row where info on the different waveforms are displayed, double tap the newly created MATH waveform, which should be labeled "Math 1," to show more details.
5. Under "Math Type," select "Advanced" by tapping it.
6. Tap the "Edit" button that appears next to the Math 1 equation entry. This will open up the Equation Editor.
7. In the Equation Editor, tap the "Add New Filter" button.
8. In the pop-up window, set the filter type to "ArbFlt" and tap "Load."
9. Navigate to the TAP1500L filter and select it. Then tap "Open."
10. Tap "OK" on the pop-up window. This will add the TAP1500L filter to the list of filters the scope can use in the Equation Editor. This only needs to be done once after resetting the scope.
11. To create the equation, tap the newly created filter entry under the "Filters" column. Then, for input, select "Channel 1."
12. The equation at the bottom of the window should look something like this:

Math 1 = ^[CoefFileName="C:/TAP1500L_filter.flt"]ArbFlt(Ch1)

13. Tap "Apply" and then "OK."

The DSP filter for the TAP1500L should now be applied to the TAP1500L currently connected to the scope. A few notes about the filter:
- The filter changes which coefficients is uses on the waveform depending on the current sample rate of the scope. The highest sample rate the filter has coefficients for is 25 GSa/s. The filter will not work for any sample rates higher than 25 GSa/s, but it will work fine for lower sample rates.
- The filter requires a minimum number of points from the input waveform before it can properly display on the screen. If you're not seeing the waveform show up on the display, try increasing your record length.
- When creating a MATH channel, the scope tends to assume what the scaling and offset of the waveform should be. Keep this in mind if you're still not seeing the waveform - you may need to quickly adjust those first.
- The filter that we send to customers and use in MQC is a nominal filter created from probes built during the NPI phase. This filter is perfectly adequate across all batches of TAP1500L, but if there is an ECR or ASEP that will cause the passive components or materials inside the probe to change, this filter will need to be recreated using probes with the new build. This should also require an updated firmware version and a check somehow to see which verison of the filter should be applied to the TAP1500L.
