Functional Check
The functional check is used to perform a quick check of the most important func-
tions of the R&S
RT
‑
ZD10/20/30 differential probe using simple measurement
equipment.
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
‑
ZD10/20/30 service 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.
