Functional Check
The functional check is used to perform a quick check of the most important func-
tions of the R&S
RT-ZS60 active voltage probe using simple measurement equip-
ment.
The following functions are checked:
●
Initialization
●
DC Offset
●
DC Accuracy
●
Offset
The functional check is not suitable for verifying compliance with the probe speci-
fications, since the test results are influenced by the oscilloscope used.
To verify compliance with the probe specifications, it is necessary to run an inde-
pendent performance test. This test is described in detail in the R&S
RT-ZS60 ser-
vice manual. The performance test also requires the R&S
RT-ZK2 service kit.
All base unit settings described here refer to an R&S RTO oscilloscope. The
use of other oscilloscopes may result in different settings and menus.
The following test description always refers to channel 1 (CH1) as the refer-
ence channel. The test can also be performed on any other channel of the
R&S RTO oscilloscope.
