The ATX7006 tester has a build in HELP feature, which gives a short description of each command. Send the command HELP for more help options. Commands can be send with e.g. ATCom7006 or ATCom7006 online. For a more information about can be found in the Online Command Reference.
The DIO module is supplied with an on board 200MHz clock source. The maximum clock frequency in low speed mode for the pattern sequencer is 100MHz. So the minimal clock divider (command CCLKDIV) for the DIO is 2. Other possible divider steps for the main clock divider are 4 and 8. For a lower pattern sequencer update rate, please use the pattern bit clock divider (command PB_CLKDIV)
The maximum throughput rate of the module is 2Msps in Warp mode, and 1.5Mhz in normal mode. The operational mode is set with COPMODE. For optimum performance it is recommended to program the falling edge of the capture clock within 70ns after the rising Capture clock edge. A minimum clock high time of 20ns should be observed. Alternatively, the capture clock high time can be programmed to at least 385ns in Warp mode or to 520ns in normal mode. In Warp mode, the time between conversions should not exceed 1ms. (minimum update rate of 1kHz).
The DPS16 module can generate a current limit error if an output voltage is programmed and the output is connected to a device. It is not recommended to do "hot-switching". It will shorten the lifetime of the output relays considerably. So please first program 0 V on the output before switching on the DPS16 output.
The current limit circuit is sensitive to abrupt and fast short circuit conditions. A fast short circuit makes append all parasitic interconnect lead inductances between the output amplifier and the load. These parasitic elements can cause significant transient voltage spikes over the current sensing circuit which can lead to polarity reversal from sourcing current limit to sinking and vice versa. In some cases, this can cause the current limit circuit to go to the incorrect current limit direction and hang up. To prevent such situations it is highly recommended to avoid hot switching. Should the current limit circuit come in this condition, then use the following command sequence to solve the current limit hang up:
