Differential probes from R&S to measure
differential and ground-referenced signals
Rohde & Schwarz is offering new differential probes
to measure differential and ground-referenced signals. Engineers
can use these differential probes to analyze the ground-referenced
or differential signals and also differential clock signals.
Rohde & Schwarz probes offer low noise of type. 3 mV
and wide dynamic range of +/- 5 V. They feature a high DC
input impedance of 1 M? and the low input capacitance (0.6
pF). Offset and gain errors are kept low throughout the
entire temperature range, which means that users do not
have to interrupt their measurements for compensation or
recalibration when temperatures vary.
The base unit can easily be controlled from the probe through
a micro button in the probe tip. Functions such as Run/Stop,
Autoset or screen dump can be assigned to this button for
easy use. The probe tip also accommodates the R&S ProbeMeter,
which delivers DC measurement results for common mode and
differential voltage regardless of the base unit's settings.
This is the first time that a differential probe enables
the user to determine the common mode operating point at
The probes can be connected to the R&S RTO and R&S
RTM oscilloscopes and also to the Rohde & Schwarz spectrum
and network analyzers by using the R&S RT-ZA9 probe
adapter. The R&S RT-ZD20 and R&S RT-ZD30 differential
probes are now available from Rohde & Schwarz.
