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