MOBILE COMMUNICATIONS MEASURING INSTRUMENTS

Adjacent channel power

?

IQ level measurement Displays the power to second adjacent channel in wide-range graph and numeric data forms. It is also possible to display the power for each channel separately. Input voltage (rms value, p-p value) for IQ can be measured.

?

Demodulation data display Demodulation data display of multiple signals including 16QAM (10 frames max.) is available per code channel. Max. 10 frames of de- modulation data can be outputted to a PC card.

?

Spectrum mask Executes pass/fail judgement using the standard line corresponding to each wireless LAN system. The level difference of the measured value or the measured level value is also displayed with its frequen- cy.

?

CCDF measurement Display pattern is selective from either CCDF for instantaneous pow- er and average power difference or APD. CCDF for 4 multi carriers can be measured.

?

Spurious Displays the measured results for the spurious, including frequency, level, judgement result (PASS/FAIL), specifications, RBW and VBW in three sweep modes, on three separate screens. Measured results are automatically judged and the PASS/FAIL is dis- played by presetting the Limit.

?

Adjacent channel power measurement When measurement is performed using a spectrum analyzer, the ad- jacent channel power is measured after passage through a built-in fil- ter (root Nyquist). A high-speed measurement method can also be selected.

?

Macro function (Batch Processing) Spurious measurement By presetting the judgement values, each item listed below is batch measured and judged automatically. For detail and specification, refer to the data sheet.

?

There are three methods: spot, sweep and search. Frequency and limit value can be set maximum 15 in the tables. The measurement results are displayed with a limit evaluation.

Modulation analysis (constellation) Parameter settings Display pattern is selective from either constellation only or constel- lation and code domain. Constellation of the code channel selected on code domain screen is displayed. This screen is used to set basic parameters such as frequency an signal type. After setting, a simple operation completes each mea- surement.

Parameter setup

?

Modulation analysis measurement [1] This setup screen is for conditions necessary for HSDPA analysis, such as modulation accuracy and code domain power measure- ment. Measurement is performed with simple operations after para- meter setup. The results required for modulation analysis such as frequency error, EVM and PCDE are all displayed on the screen. Also, a user can view the constellation of a code selected on the code domain screen.

?

Modulation analysis (vector error) Display pattern is selective from either vector error only or vector er- ror and code domain. Residual vector error (rms) is 1% (typ.), en- abling high-accuracy measurement.

?

Code domain analysis Code vs Slot can be displayed as well as normal code domain analy- sis display. http://www.anritsu.com 306
