33 Startup Sequence Operating Modes

The test tool sequences through the following steps when power is applied (see Figure 3-2 and Figure 9-9 (Power Circuit). 1. The P-ASIC is directly powered by the battery or power adapter voltage VBAT (pin 60). Initially the Fly Back Converter is off, and the D-ASIC is powered by supply voltage +3V3GAR. The +3V3GAR voltage is derived from VBAT by the 3V3 Supply circuit (V4000). If the voltage +3V3GAR is below 3.05 V, the P-ASIC signals this to the D-ASIC pin 64(VDDVAL line low), and the D-ASIC...

To check if the battery has a correct capacity

Do a battery refresh USER, OPTIONS , Battery Refresh 2. Disconnect the BC190 Battery Charger Power Adapter 4. When the battery is discharged the ScopeMeter will shut down. Now connect the BC190, turn the power on and check the length of the TrendPlot trace. For a new battery pack this should be about 4 hours. Depending on the number of applied charge cycles the battery capacity will decrease. If the TrendPlot trace has a length of 3 hours or less you may consider to replace the battery pack.

Battery is discharged when Scope Meter is not used for some time 2 or 3 weeks

Turn the ScopeMeter on (battery power only) 2. Check the voltage across R4101 (near the battery connector) for about 0.15 mV. This corresponds to a current of about 1 mA. Turn the ScopeMeter off and on, and check the voltage again for 0.15 mV. Do this about 10 times. If one or more times a current of about 1.2 mV is measured (8 mA), the cause is a defective IC D3550. This IC takes care of a correct power state of D3500. As the 8 mA discharge current can have damaged the battery, you must check...

Slow ADC

With the Slow ADC the D-ASIC can measure various signals for control and test puposes D4300 pin 12-15 battery current (BATCUR), battery voltage (BATVOLT), battery temperature (BATTEMP), battery identity (BATIDENT). D4300 pin 1 REFADCT can be measured for calibration and test purposes. D4300 pin 5 the internal test tool temperature is monitored by measuring the voltage on the PTC silicon sensor V4205. The result is used for control purposes, for example to control the LCD contrast. D4300 pin 4...

Sony D3202 Ringer Solution

Capacitors of 0 pF, and resistors of 100 MQ shown in circuit diagrams are not placed on the PCA. They are drawn in the circuit diagrams for PCA layout purposes. In the layout design process they create locations on the PCA where capacitors or resistors can be placed. 3.4.1 Scope Channel A - Scope Channel B See circuit diagrams Figure 9-1 and Figure 9-2. As the Scope Channel A and B circuits are identical, a description is given for Scope Channel A only. The Channel A B circuitry is built-up...
