Description
Many older test racks still talk over GPIB. A Rohde & Schwarz UDS500-G multimeter fits into them, and it also offers USB and LAN for newer setups. It is a 5.5-digit bench meter, so one model can serve both the old rack and the new one.
Ratings in short
- Resolution: 5.5 digits.
- Basic DC accuracy: 0.015%.
- DC voltage: up to 1000 V.
- AC voltage: up to 750 V RMS.
- Current: up to 10 A.
- Interfaces: USB, LAN and IEEE-488 (GPIB).
Accuracy depends on range, function, integration time, temperature and test leads. For uncertainty budgets, use the full data sheet, and keep a safe margin below the instrument limits.
Functions you can count on
The meter reads DC and AC voltage, DC and AC current, capacitance, frequency and temperature. It also measures resistance with two wires or four. Use the four-wire mode for low resistances, because it removes the error from lead resistance.
Pick the range and integration time for the balance you want. Slower integration lowers noise, while faster settings suit production loops.
Wiring the Rohde & Schwarz UDS500-G multimeter into a rack
The GPIB port suits systems built around older controllers. The USB and LAN ports handle data logging from a computer. Before you order, note the command set, trigger method, sampling plan and file format your software expects.
Then think about safety. Choose the right input jack first, and respect the terminal ratings, category limits and current-fuse values. Make connections while hazardous sources are off.
Rental, purchase and service
Lost in HCM lists the UDS500-G for rental and sale, and it arranges service on request. A line-bring-up project fits a rental, while a permanent station may call for a purchase. In either case, ask what calibration paperwork is available for the unit you are offered.

Rohde & Schwarz UDS500-G multimeter questions
Which interfaces does the UDS500-G have?
USB, LAN and IEEE-488 (GPIB). The GPIB port is what sets the -G model apart.
What is the highest DC voltage it measures?
It measures DC voltage up to 1000 V, within the published ranges.
Can it measure low resistance accurately?
Yes, with four-wire resistance, which removes the effect of lead resistance.
