It provides detailed instructions on how to configure and use these functions, emphasizing the importance of setting static values correctly before ramp generation and the use of IU tables to set DC output current based on voltage.

IU Table Function:
The IU function allows setting a DC output current dependent on the DC output voltage using a table with 4096 values. Only the first 3342 values are effective due to current limits. The table can be uploaded via USB or remote control, and must meet specific format requirements, including being a CSV file with 4096 values.

PV Function:
This function simulates solar panels using an XY generator and IU table. It calculates an IU table from typical solar cell values and allows adjustment of a parameter called Irradiance to simulate different light conditions. Key parameters include short-circuit current (ISC), open circuit voltage (UOC), and maximum power point (MPP).

FC Table Function:
The FC table function simulates fuel cell characteristics by setting parameters for four support points on a typical fuel cell curve. The voltage must decrease and current increase across these points. Incorrect settings will result in errors.

Extended PV Function:
According to EN 50530, this function simulates solar panels for testing solar inverters. It offers more parameters and allows data recording. Users can select between different panel technologies and simulation modes, with specific defaults for each technology.

Key Recommendations:

- Utilize the extended PV function for comprehensive solar inverter testing.

Simulation Modes: The document describes various simulation modes for analyzing solar panel performance. The E/T Controllable simulation allows adjustment of irradiation and temperature during runtime, affecting the Maximum Power Point (MPP). The DAY U/I and DAY E/T modes process day trend curves with up to 100,000 points, defined by voltage, current, irradiation, temperature, and time.

Day Trend Simulation: This mode is used for long-term tests, processing a curve with up to 100,000 user-definable points. Each point is defined by three values, including dwell time. Interpolation can be activated to calculate intermediate points, ensuring smoother transitions between curve points.

CSV File Configuration: For DAY E/T and DAY U/I modes, specific CSV file formats are required. The files must adhere to regional settings for number and column separators. The DAY E/T mode requires columns for index, irradiance, temperature, and dwell time, while DAY U/I requires columns for index, voltage, current, and dwell time.

Data Recording: Data can be recorded during simulations and stored on a USB stick or read via a digital interface. The device records data every 100 ms, with a maximum of 576,000 data sets, allowing for up to 16 hours of recording.

Configuration Steps: The configuration involves selecting panel technology, input mode, and simulation mode. For DAY E/T or DAY U/I modes, day trend data must be loaded from a USB stick. The recording feature can be enabled to collect additional data.

Simulation Control: After configuration, the simulation can be controlled via the function generator. The simulation parameters can be adjusted directly, and the simulation can be started or stopped based on specific criteria, such as device alarms.

Test Analysis: After the simulation, recorded data can be saved or read for analysis. The data helps visualize and determine characteristics of the simulated solar panel and inverter.

Remote Control: The function generator can be remotely controlled, with specific commands differing from manual operation. The external documentation provides guidance on remote control.

Safety notices • Electrical equipment operation means that some parts accessible on the outside of the device can be under high voltage. Therefore all parts under voltage must be covered during operation! This basically applies to all models, except for the 60 V model according to SELV. • The DC terminal is isolated from the AC input and not connected to ground internally. Hence there can be dangerous potential between the DC poles and PE, for instance caused by a connected external source application. Due to charged capacitors this could even be true if the DC output or the device are already...
