Ω
Output
See (9) in Figure 5-1 .
Output of the tracking generator. Connect the DUT using a cable equipped with a male
N
connector.
Risk of damaging the tracking generator
See the data sheet for the limits of the DC voltage and reverse RF power. Do not
exceed these limits. Exceeding these limits can cause instrument damage.
For DUTs with sensitive RF characteristics with regard to matching (VSWR) at the
input, insert a 10
dB attenuator between the DUT and the tracking generator.
5.1.10 USB Interfaces
See (10) in Figure 5-1 .
USB (universal serial bus) interfaces of the type A (host USB). Used to connect exter-
nal devices as described in
Chapter 6.3, "Connecting USB External Devices" ,
on page 39.
The USB version depends on the serial number of the R&S ETL:
●
< 205 000: USB 1.1
● ≥
205 000: USB 2.0
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, make sure that the conditions described in
Chapter 6.1, "Preventing Electro-
magnetic Interference" , on page 37 are met.
