PSB 9000 3U Series
3.11.13.4 Mode MPP4
This mode is different to the others, because it does not track automatically. It rather offers the choice to define
a user curve by setting up to 100 points of voltage values, then track this curve, measure current and power and
return the results in up to 100 sets of acquired data. The curve points can be entered manually or loaded from
USB stick. Start and end point can be adjusted as well, Δt defines the time between two points and the function run
can be repeated up to 65535 times. Once the function stops at the end or due to manual interrupt, the DC input is
switched off and the measured data is made available. After the function, the acquired set of data with the highest
actual power will be shown in the display as voltage (U
MPP
), current (I
MPP
) and power (P
MPP
) of the MPP. Going back
on the screen with RETURN then allows for data export of the 100 measured results to USB stick.
Following parameters can be configured for tracking mode

3.11.14 Remote control of the function generator
The function generator can be remotely controlled, but configuration and control of the functions with individual
commands is different from manual operation. The external documentation “Programming Guide ModBus & SCPI”
on the included USB stick explains the approach. In general the following items apply:
•
The function generator is not controllable via the analog interface
•
The function generator is unavailable if R mode (resistance) is activated
•
Function “Battery test” is not available for remote control
