3GPP FDD code domain power measurements<br />
on base stations<br />
The ¸<strong>FSH</strong>-K4 option 1) allows code domain power measurements on a<br />
3GPP base station. It measures the total power and the power of the most<br />
important code channels, such as the common pilot channel (CPICH), primary<br />
common control physical channel (P-CCPCH), primary synchronization channel<br />
(P-SCH), and secondary synchronization channel (S-SCH). Furthermore, the<br />
carrier frequency offset and the error vector magnitude (EVM) are measured<br />
and displayed. The scrambling code can be determined at the press of a button<br />
and used automatically for decoding the code channels. The user can also<br />
get a quick overview of adjacent base stations. The ¸<strong>FSH</strong> can display up<br />
to eight scrambling codes with their CPICH power. The ¸<strong>FSH</strong>-K4 option<br />
provides automatic level setting for fast and optimal setting of the reference<br />
level. In practice, this means very easy operation. To display the code domain<br />
power measurement values, only four operating steps are necessary:<br />

For base stations with two antennas, the user can select which antenna the<br />
¸<strong>FSH</strong> should synchronize to (antenna diversity).<br />
Locating EMC weak spots<br />
The ¸HZ-15 near-field probe set is a diagnostic tool for locating EMC<br />
weak spots on printed boards, integrated circuits, cables, shieldings, and<br />
other trouble spots. The ¸HZ-15 near-field probe set can handle emission<br />
measurements from 30 MHz to 3 GHz. Its sensitivity can be enhanced by adding<br />
the ¸HZ-16 preamplifier, which has a frequency range of up to 3 GHz, a<br />
gain of approx. 20 dB, and a noise figure of 4.5 dB. In combination with the<br />
¸<strong>FSH</strong>, the preamplifier and near-field probe set are a cost-effective means<br />
of analyzing and locating sources of interference during development.<br />
