The MEM:TABL:READ query is a SpikeSafe-specific SCPI query to obtain status information for all SpikeSafe channels. This information includes the current bulk voltage, channel voltage, channel current, and channel state. The temperatures of each heat sink are also obtained by this query.
Demonstrate proper usage of the "Get SpikeSafe Status" query on the SpikeSafe. During typical operation, the MEM:TABL:READ query should be sent periodically while the SpikeSafe is connected in order to monitor temperature and power output. This is especially useful when one or more SpikeSafe channels are enabled.
A Get SpikeSafe Status query will be sent, and its response will be read. This typically looks similar to the text shown below if connected to a one-channel SpikeSafe and that channel is enabled. Here the 1 channel SpikeSafe bulk voltage is 100.1V; Channel 1 displays 10.024510V, 10.001mA, and is enabled; and Heat Sink Temperature 1 measures 27.1°C.
