Ram

Measurement data and instrument settings are stored in RAM D475. All RAM data will be lost if all power sources (battery and power adapter) are removed. The D-ASIC has on-chip mask ROM. If no valid Flash ROM software is present when the test tool is turned on, the mask ROM software will become activate. The test tool can be forced to stay in the mask ROM software by pressing the A and > key, and then turning the test tool on. When active, the mask ROM software generates a 100 kHz square wave...

The unidirectional SDA-SCL serial bus (pin 56, 57) is used to send control data to the C-ASIC's (e.g. change attenuation factor), and the T-ASIC (e.g. select other trigger source). The SDA line transmits the data bursts, the SCL line transmits the synchronization clock (1.25 MHz). Via the probe detection inputs PROBE-A and PROBE-B (pin 54, 55), the D-ASIC detects if the Input A and B probes have been connected disconnected. The SUPPRDET signal (pin 99) can suppress the probe detection. If this...
