NOP: No Operation
No operation is performed when this action is received.
IPR: Individual Parameter Request
Indicates an individual parameter value send request message. When the Instrument receives this action, it uses an IPS
message to return the specified parameter value.
IPS: Individual Parameter Send
Indicates an individual parameter value send message. When the Instrument receives this action, it rewrites the value specified
by the data field with the specified parameter value.
OBR: Oneway Bulk Parameter Set Request
Indicates a send request message using parameter set image one-way mode. When the Instrument receives this action, it
uses an OBS message to return the specified parameter set.
Though OBR is defined as a series common format, one-way mode transfer is not supported by this Instrument.
OBS: Oneway Bulk Parameter Set Send
Indicates a parameter set image send message using one-way mode. The parameter set to be transferred is divided into
multiple packets when it is greater than a prescribed size. The packets are transferred at fixed intervals.
Though OBS is defined as a series common format, one-way mode transfer is not supported by this Instrument.
HBR: Handshake Bulk Parameter Set Request
Indicates a send request message using the parameter set image handshake mode. When the Instrument receives this action,
it uses an HBS message to return the specified parameter set.
HBS: Handshake Bulk Parameter Set Send
Indicates a parameter set image send message using handshake mode. The parameter set to be transferred is divided into
multiple packets when it is greater than a prescribed size. The packets are transferred in accordance with handshake mode.
ACK: Acknowledge
Indicates a message used by the receiver during parameter set handshake mode transfer to convey to the sender that it is
ready for send of the next packet. The cat, mem, and pset fields indicate the value carried by the last received message.
