DSO203 GCC APP - Community Edition (2.51+SmTech1.8+Fixes)

[Wildcat]

When saving a configuration file (SaveFile 000.CFG), program prompts user with “OK” but immediately increments CH(A) mode setting (DC/AC/DT/TL/RS/) (e.g., DC → AC, AC → DT, etc). The saved configuration file must be reloaded, to restore the Channel A mode setting.

Yes it does! Never noticed this, if you use the center press left toggle button to save a config file it advances the setting

if any of the menus are set to the 2nd position. I tend to press the same button again (#3) to save config files, and it does not do it that way, so I never noticed it… You don’t need to reload a config file to change it back though, just flip the toggle left. Will be checking into it.

Analog Calibration can be confusing.

• After calibrating DC-offsets and gains, user is incorrectly prompted (at header) to press button 2 to “confirm the re-calibration of Ch_A “. This is confusing, as user might think program needs confirmation of user inputed calibration data. At footer, user is also prompted to use right toggle to “select the next operation”. Header prompt should instead say “restart re-calibration of Ch_A”. If user incorrectly confirms re-calibration, all previously entered data is lost and must be re-entered. User must right toggle twice (<-) to find “Press button 2” or “3” to save calibration data.
  

This is a carry-over from the original programming, I never changed it. The original English was a bit strange. I can change the wording around.

Wildcat User Guide does not cover or explain if Ch_A / Ch_B calibrations should be performed separately or together. Preference is to do Ch_A and Ch_B independently, as the battery level may run low while trying to do both channels at once. Note: Calibration mode is accessed with long-press of button 2, only when Ch_A or Ch_B are selected. If Ch_B is selected, calibration is entered already set for Ch_B, likewise for Ch_A. It is however possible to switch from Ch_A to Ch_B within Calibration mode in order to populate both calibration tables before saving to WPT file.

I’m not sure if your concern with the battery running low is because it could run out and turn the device off, or if it will affect calibration. As far as calibration is concerned, if I remember right, when saving one channel, the battery level affecting the other channel if it was also calibrated is taken into consideration as far as the battery may now, after time spent calibrating the second channel, be a bit lower. The battery level does not have to be very close to the exhaustion point to set the low level, say maybe 1/4 charge or a bit more should be ok. Battery levels are recorded at calibration

saving point and used as a reference. If the high battery level calibration is done while charging, the VB+ line will be high enough for good interpolation/extrapolation with a low bat level even at 1/2 charge.

Left toggle button beeps can be annoying and should be muted during gain calibration steps. This is especially annoying if no previous calibration data exists

OK, I suppose they could be muted as they don’t serve any function. This is again a carry over from the original version, not done on purpose.

What’s with the bootup “Reload parameter from disk”. Anyone know what that means?

This is also a carry-over from the original, it simply means that the start-up config file was found and used to set configuration. If no config file is found it reads “Parameter record not found”. I DID correct the original spelling that stated “Reload parameter form disk”



I appreciate the feedback! Will be posting an update shortly, which will contain a few other fixes as well (in particular a triggering issue while serial decoding in large buffer mode on the 500uS timebase), as well as added SPI and I2C decoding. Will keep all this in mind.
