REV?

Purpose To request the main and front panel revision levels.

Format REV?

Response Main ﬁrmware revision/Front panel ﬁrmware revision

Description The REV? query allows you to request both the main processor ﬁrmware revision level, and the front

panel display controller ﬁrmware revision level. The instrument returns two numbers separated by a

slash: (1) the main processor ﬁrmware revision level, and (2) the front panel display controller ﬁrm-

ware revision level.

The response form used by the Model 2002 is different from that of the HP3458A.

RMEM?

Purpose To request readings stored in memory.

Format RMEM?

Response Reading #1, Reading #2, ... Reading #n

Description The RMEM? query returns all readings currently stored in memory. Note that the format of readings

returned differs from that of the HP3458A. The Model 2002 returns all readings in one text block,

separated by commas, with a string terminator only at the end of the block. The HP3458 includes a

terminator between each reading. Also note that this command has been changed to a query-only

format.

RQS
