The manual covers the setup and operation of the DPS and DPSP RF step attenuators, detailing their ability to perform precise attenuation, gain, and sensitivity measurements in the frequency range from DC to 2700 MHz. It also provides troubleshooting information, highlighting the devices' high accuracy, low residual attenuation, and long service life of over 10 million switching operations, with the DPSP being programmable and compatible with the IEC bus for automated testing systems.
Manual Overview
The operation manual for the Rohde & Schwarz DPS and DPSP RF Step Attenuators provides detailed instructions on their use for precise attenuation, gain, and sensitivity measurements within a frequency range of 0 to 2700 MHz. Both models offer attenuation steps of 1 dB, ensuring high accuracy and reliability, even at maximum attenuation levels. The DPS model is manually operated via decade switches and is suitable for mobile use due to its rechargeable batteries. The DPSP model, on the other hand, features programmable operation with rotary switches and automatic carryover, controlled by a microprocessor. It also includes an IEC-bus interface for integration into automated test systems. The manual emphasizes the devices’ long service life, capable of withstanding over 10 million switching operations. Troubleshooting focuses on ensuring proper connection and operation through the IEC-bus, with diagnostics primarily involving checking switch settings and connections. Calibration and adjustments are facilitated by the precision of the devices, with minimal need for recalibration due to their robust design.
Quick Issues Covered
- DPSP supports remote control via IEC-bus for diagnostics.
- Manual and programmable attenuation adjustments from 0 to 139 dB.
- Power-up failures may involve battery recharge issues in DPS model.
Overview
The product is a high-precision RF Step Attenuator available in two models, DPS and DPSP, covering a frequency range from DC to 2700 MHz.

Operation
The RF Step Attenuators DPS and DPSP are designed for use in the frequency range from DC to 2700 MHz. They are used for measurements of attenuation, gain, and sensitivity, as well as the reduction of voltages to small and defined values. Both models allow setting attenuation values from 0 to 139 dB in 1 dB steps, with high accuracy and low residual attenuation. The DPS is manually operated using decade switches and includes rechargeable batteries for mobile use. The DPSP can be manually operated with rotary switches and is also remotely controllable via an IEC bus interface. It is suitable for integration into 19″ racks and features automatic carryover controlled by a microprocessor. Both models have low reflection inputs and outputs, and the RF connectors can be rerouted from the front to the rear panel without additional parts. The carrying handle can be used as a stand or removed.
