Adjust the measurement equipment for power level tuning. Remember to take jig and RF cable attenuations into account! Choose Data rate 6 Mbit/s. It should be 6 Mbit/s, otherwise power levels for other datarates will be miscalculated!. Click Start. Page 5 –14 COMPANY CONFIDENTIAL Issue 1 Copyright © 2007 Nokia. All rights reserved.

Note: WLAN Tx power Level tuning is only allowed with adequate measurement equipment. WLAN functionality testing using SB-7 WLAN test BOX with RX-44 Context The build-up and usage of the WLAN Test Box SB-7 is described. A simple functionality test is advised. With this test both WLAN RX/TX will be tested in weakened field scenario.
Page 142 1. The cover of SB-7 contains a grid starting from A1 and ending to Q17 (see figure 7). Place CU4/SS-62 + FS-66 on SB-7 so, that the corners of SB-7 are on top of the following square of the grid: A5, A13, O4 and O14. Page 5 –16 COMPANY CONFIDENTIAL Issue 1 Copyright © 2007 Nokia.

SW). Power distribution Generally, RX-44 EM architecture is implemented with three EM ASICs, EM ASIC Vilma D1420, EM ASIC Betty N1310 and EM ASIC Menelaus N4200 controlling the EM and supplying the output voltages. In addition to the ASICs, N5351 PM ASIC handles the power supply for HS USB controller.
Page 162: Clocking Scheme And Controlling Signals
There are two main clocks in the BB system: 19.2 MHz square wave clock provided by discrete oscillator and 32.678 kHz sleep clock produced by the EM ASIC D1420 with an external crystal. Page 7 –8 COMPANY CONFIDENTIAL Issue 1 Copyright © 2007 Nokia. All rights reserved.

The device provides acoustical stereo audio output via integrated dynamic speakers and electrical calvanic stereo audio output via 3.5mm Nokia AV interface. Analog audio signal capture is handled by internal digital microphone and via Nokia AV interface using headset’s microphone, such as Nokia HS-48.
Page 171: Internal Speakers
The D4800 feeds digital audio data to the N4100 via the I2S interface. After the N4100 the signal is further amplified by stereo audio power amplifier (N4101) and fed to the dynamic speakers (B4140 and B4141). Issue 1 COMPANY CONFIDENTIAL Page 7 –17 Copyright © 2007 Nokia. All rights reserved.

Figure 47 Nokia AV interface, output Nokia AV interface, input Traditional analog electret type of microphone is supported by the Nokia AV interface. The microphone is biased by the 2.1Vdc from the D1420 asic. The weak analog audio signal got from the microphone is fed to the N4100, amplified, AD converted and passed to the D400 for further usage via the I2S interface.
