How can I Express an Arbitrary Exponentiation Other Than the Square and Cube Computation Function in XViewer?
Solution:
You can express any arbitrary exponentiation, in Xviewer or DL series instruments, by using the LOG (common logarithm) and EXP (exponential) functions. For example, for C1 raised to the exponent of 0.2, the math function in Xviewer would be:
EXP(LOG(C1)/LOG(2.71828)*0.2)
EXP(LOG(C1)/LOG(2.71828)*0.2)
The LOG and EXP functions in Xviewer can be found by following these procedures:
- Click on Analysis ⇒ Math Setting
- Click on the Expression Field
- Click on ...
- Click on Basic
- Select EXP or LOG
Related Information
This method also applies to the WE7000 Computation Waveform Viewer and the User-Defined Computation of the DL750/DL750P and DL7480/DL7440. The method for the Dl9000, DLM6000 and DLM2000 instruments is different since they have a natural logarithm function LN. For the example previously mentioned, C1 raised to the exponent 0.2 would be expressed as:
EXP(LN(C1)*0.2)
