67 | * cmdset_hp is used for the 34401A, which was added to this code after the | |
68 | * 34405A and 34465A. It differs in starting the measurement with INIT: using | |
69 | * MEAS without a trailing '?' (as used for the 34405A) is not valid for the | |
70 | * 34401A and gives an error. | |
71 | * I'm surprised the same instruction sequence doesn't work and INIT may | |
72 | * work for both, but I don't have the others to re-test. | |
73 | * | |
74 | * cmdset_hp also works well for the 34410A, using cmdset_agilent throws an | |
75 | * error on 'MEAS' without a '?'. | |
76 | * | |
77 | * On the 34401A, | |
78 | * MEAS <optional parameters> ? configures, arms, triggers and waits | |
79 | * for a reading | |
80 | * CONF <parameters> configures | |
81 | * INIT prepares for triggering (trigger mode is not set, assumed | |
82 | * internal - external might time out) | |
83 | * *OPC waits for completion, and | |
84 | * READ? retrieves the result | |
