I have an old Tektronix DSO ( Digital Storage Oscilloscope ) TDS310 wiht RS232 serial port. I wrote an application
named TDS.exe to get Measurements from TDS310. I have written Program TDS298 ver188.8.131.52 to get measurements of
Tektronix DSO or Renesas MCU (Micro Controller Unit) H8/36x4F A/D outputs at every minute synchronized by PC calender
clock, and write the result of measurements in text file of Meas.txt. PC calender clock is very precise with NTP
(Network Time Protocol). It corrects PC clock in arbitrary time. TDS298 can also samples at arbitrary timer period.
TDS298 supports H8/3664F and Slip21 draws realtime chart
Program Slip21 shows the history of Measurements the latest first order and real-time chart. Slip21 is new version of
Slip2. I had to give up supporting Win95/98 to show real-time chart for WinXP. Now TDS298 supports Win7 instead of
Win95/98. Setup of TDS310 are 5KS/s ( 10ms/div ), 500 mV/div, no averaging sample. I measured outputs of two solar
cells on 18 Febrauary 2012 (GMT+9). The first column is record number. The second column is date of yymmdd. The last
four digits shows hh:mm. The following four columns are M1, M2, M3 and M4. I copied the output saved in
Solar120218.txt in the list box of Slip2. Program Slip2 writes htm formatted table
automatically. TDS298 can get A/D outputs of MPU Renesas H8/36x4 now, as I wrote a RS232 and A/D program
for the MCU. I show the sreen shots of TDS298 and Slip21.

Tbl.1 Mode of Measurements
WinXP doesn't show chart properly developed by VB4
I was programming application Slip298 for Win95/98 and WinXP that shows real-time chart and the history of Measurements. I gave up drawing a chart that Slip298 works on Win95/98 and WinXP. So I have programmed Slip21 for WinXP/7 instead of Slip298.

I found that TDS298 developed by VB4+Win98 does not show a chart well on WinXP. Probably graph control does not work on WinXP properly. The graph control is done by GRAPH32.OCX, GSW32.EXE and GSWDLL32.DLL. So I migrated Slip298 for VB2010. I eliminated intermediate Kiri198 and renamed Slip2 for Slip21. CNET appoved it, and you can download.
MCU board is superior than DSO for long time measurement
The table shows the comparision with MCU 3664F and DSO TDS310 from the view of long term measurement. I bought TDS310 more than 15 years ago. There is my old TDS310 on a shelf. The shelf is taller than my head when I sit on chair. The big blower makes big noise. TDS310 emits more than 60W. While AKI-H8/3664F works at measured 0.06W only. It may dissipate less than 1W including power loss of power supply. The least enrgy comsumption is favor in Japanese tropical summer. TDS310 has two 8-bit A/D for 2CH and measures 2CH at the same time. 3664F has a 10-bit A/D with 4CH multiplexer. It scans 4 inputs fast.

Tbl.2 Comparision 3664F and TDS310
Slip applied to record charging voltage for Ni-MH batteries
I sometimes charge a pair of Ni-MH batteries called Eneloop for Xbox360 wireless controller. I measured the power supply and application voltage as Measurement1 and Measurement2 of Tektronix DSO TDS310 with my tiny voltatge regulator. TDS298, Kiri198 got their Measurements. Slip2 listed and recorded the Measurements. I started the measurement at 00:02 on 6 March. Then the application voltage was 2.361V. I finished charging at the application voltage of 2.820V at 11:04, because the charged voltage reached 1.40V per battery. I copied the list and pasted in text file that I show you. The setup of TDS310 are 2KS/s ( 25ms/div ), 500 mV/div, 16 averaging sample.
