Rohde & Schwarz Part Numbers Explained: 1321, 1323, 5601 Series Guide
If you work with RF test equipment, you have likely seen part numbers like:
- 1321.1111.02
- 1323.1890.02
- 5601.4007.05
- 1304.0004.03
These are not product models. They are internal material numbers used to identify components inside Rohde & Schwarz instruments.
What Are R&S Part Numbers?
Rohde & Schwarz uses structured material codes to manage internal components, spare parts, and repair modules.
These part numbers are essential for:
- Equipment repair
- Spare parts sourcing
- Module replacement
- Inventory management
Understanding the Structure
Most part numbers follow this format:
XXXX.XXXX.XX
This typically represents:
- Product group
- Module type
- Revision/version
Key Part Number Categories
1. 1321 / 1323 / 1328 Series – Core Modules
- RF processing boards
- IF modules
- Digital signal boards
- CPU / FPGA units
These are the most critical and high-demand components.
2. 5601 / 5800 Series – RF Front-End
- Amplifiers
- Attenuators
- Mixers
3. 1304 / 1309 / 1314 Series – Power & Interface
- Power supply modules
- LAN / GPIB / USB boards
4. 1801 / 1802 / 1803 Series – Logic Boards
- Main control systems
- Embedded processing units
5. 0272 / 0358 Series – Connectors
