DM15L Progs
Dumps taken from the DM15L using a serial console session in Putty.
Stock Swiss Micros Firmware
Dumps are also converted to readable program listings using the Swiss Micros online encode/decode tool at https://technical.swissmicros.com/decoders/nut/
Normal + "Complex Z to....."
LBL E converts Z=R±jX to RL, SWR, |ρ|∠ρ, |Z|∠Z
Data input :
if Z = R + j X, put R in Y-stack and X in X-stack and then run LBL E
- R ENTER
- X (and CHS as needed)
- F
- E
Results appear:
- Stack X → Return Loss
- Stack Y → SWR
- Stack Z → (Re) |ρ| (Im) ∠ρ
- Stack T → (Re) |Z| (Im) ∠Z
