Specifications, setup and FAQ
Rohde & Schwarz NGL202 is a 2-channel high-precision dc power supply with up to 120 W total output. Its linear regulation, source and sink operation, standard data logging, remote sensing, USB and LAN interfaces suit sensitive DUTs and battery-oriented tests. This guide summarizes the model-specific limits and helps prepare a rental, repair or purchase enquiry in Vietnam.

NGL202 specifications at a glance
| Model | NGL202 |
|---|---|
| Manufacturer | Rohde & Schwarz |
| Manufacturer order number | 3638.3376.03 |
| Instrument type | High-precision DC power supply |
| Output channels | 2 |
| Total output power | 120 W maximum |
| Maximum channel power | 60 W |
| Voltage range per channel | 0 V to 20 V |
| Current range per channel | Up to 6 A at 6 V or below; up to 3 A above 6 V |
| Operating quadrants | Two-quadrant source and sink |
The 60 W channel limit means headline voltage and current values cannot be used simultaneously. Calculate voltage multiplied by current for the intended load. Leave margin for startup current, transients and test conditions. When the instrument sinks current, also confirm the applicable sink limits and energy flow described in the operating manual.
Choose the right NGL202 configuration
Its linear regulation, source and sink operation, standard data logging, remote sensing, USB and LAN interfaces suit sensitive DUTs and battery-oriented tests.
List the normal voltage, peak current, average current and transient behavior of each DUT rail. Confirm whether the test needs source operation, sink operation, remote sensing, triggering, logging or an external measurement input. Optional software and hardware functions should be named explicitly in the quotation instead of assumed from the base model.
For automated work, record the interface, command set, firmware and expected sample rate. For manual troubleshooting, specify the displayed measurements and protection behavior needed by the operator. These details help distinguish a simple power-up test from a battery simulation, current profiling or source-measure workflow.

This is a functional connection guide, not an internal service schematic. DUT means device under test. Follow the manufacturer manual for terminal assignments, polarity, grounding, remote sensing and safe source/sink operation. Disable the output before changing connections and use leads rated for the voltage, current and expected fault conditions.
Plan a repeatable source-measure test
- Define the voltage, current, power and sink limits before connecting the DUT.
- Check polarity, grounding and sense connections with the output disabled.
- Set overvoltage, overcurrent and overpower protection appropriate to the DUT.
- Enable the output using the documented procedure and observe voltage, current and operating quadrant.
- Record settings, firmware, logging rate, fixture and environmental conditions with the result.
When capturing fast current changes, choose a logging mode and sample rate appropriate to the event. Keep the raw data with timestamps and note any filtering or averaging. For battery or load emulation, document the programmed curve, initial state and stop conditions so the test can be reproduced safely.

NGL202 FAQ
How many outputs does the NGL202 have?
The NGL202 has 2 output channels and a maximum total output power of 120 W.
Can the NGL202 supply maximum voltage and current together?
No. Each channel is limited to 60 W. The current limit also changes with voltage: up to 6 a at 6 v or below; up to 3 a above 6 v. Confirm every operating point against the manufacturer specifications.
Can the NGL202 operate as a load?
Yes. Its two-quadrant architecture can source or sink current within the specified operating limits. Follow the operating manual when connecting an external source or battery.
Can I request a NGL202 rental in Vietnam?
Send the required dates, delivery location, current and voltage range, interfaces and documentation needs to Lost in HCM. Rental availability and the supplied configuration require quotation confirmation.
What is the manufacturer order number for NGL202?
The manufacturer lists order number 3638.3376.03. Options, interfaces, rack accessories and software functions are ordered separately where applicable.
