I am using GPIB to send measurement query commands to the N6700B power supply. This is happening fairly often (every second). When this happens, the front panel randomly refreshes its voltage and current display (showing "------" in place of measurements, then re-displaying correct values). Is there any way to circumvent this issue, aside from decreasing the measurement frequency?
Since you are taking measurements quickly over GPIB, the measurement system is engaged in providing those measurements. What you are seeing is an instance where the front panel is trying to refresh while you are taking a GPIB measurement. This is normal operation. Unfortunately, the only way around it would be to decrease your measurement frequency.
Please let us know if you have any other questions or concerns.
