Example:
saving a ramp that starts from -10V and ends in +9.98V (see below more details
concerning the ramp duration).
Save an Excel file with values as follows:
A1 = -10
Ai
+1
= Ai + 0.02 (i=1…999)
This file contains 1000 values in column A, in increments of 0.02. The first value in A1= -10
and the last value in A1000 = +9.98
Save this file as RAMP.CSV
13.3.2 Long waveforms, up to 32K points:
1.
Using paradigm 9, the MEM memory of channel 9 contains 32K points (=32,768 points).
Each point has a value in the range of -10 to +10, with maximum of 2 digits following the
decimal point. These values express output voltage levels (e.g. -1.23 expresses -1.23 volts).
2.
In an Excel file, insert the values that you want, starting A1. You can use any number of
values up to 32,768 values. Save this file with the extension .CSV
13.3.3 Downloading the waveform from the PC to Master-9
1.
Connect the Master-9 unit to the PC using the USB cable and run the
MASTER-9 CONTROL
software (see the chapter 13).
2.
In the menu bar, go to PARADIGM, then to LOAD SCV FILE TO CHANNEL 9 and browse
to the desired CSV file (e.g. RAMP.CSV that was saved in 12.5.1). This saves the waveform
in the MEM memory of channel 9.
3.
You can now disconnect the Master-9 from the PC.
13.3.4 Running the saved waveform
First, switch channel 9 to the MEM mode as follows:
1.
Press the “RUN” key, and then press “MEM”.
2.
Channel 9 will now deliver the saved waveform. The 1000 points that were saved elapse
during the set DURATION time of channel 9 – (e.g., if D9=1 msec the waveform elapses 1
msec, which is 1 µsec from one point to the next).
Example 1
: After saving the RAMP.CSV file from the example above, switch channel 9 to MEM
as described. Set channel 9 to run in the FREE-RUN mode, with D9=10 msec and I9=50 msec.
Channel 9 delivers the ramp that was saved (in 12.5.2). The ramp duration is now 10 msec.
If you modify to D9=40 msec, the ramp duration will also be modified to 40 msec.
Example 2 - Sine Wave
:
You can download an Excel file with a sine wave waveform from our website: www.ampi.co.il
1.
Go to DOWNLOADS and select DOWNLOADS FOR Master-9. Download the EXCEL
FILES FOR CHANNEL 9 folder.
2.
Open the downloaded folder, save the SINE.CSV file in channel 9 as described above, and
follow the instructions in the SINE.DOC file.
