Notes:
1. A numeric entry is required by these GPIB codes, followed by the code EN (ENTER).
2. This GPIB code uses the next 6 characters (0-9, A-Z, or an underscore) as input data.
3. The asterisk (*) must be included as part of the GPIB command string.
4. The 8650A can always measure over its entire dynamic range; there is no need to specify the range. Therefore, range-related
commands have no effect on the measurement capability of the 8650A. The auto range, range hold, and set range
commands only offset the analog output voltage, and only in HP436, HP437, or HP438 GPIB emulation modes. In these
emulation modes (when using a single sensor, and not measuring in a relative mode), the power will be scaled to a range of 0
to 1 volts, representing the relative power within the current 10 dB range of the 8650A. The range hold and set range
commands will simulate locking the range of power represented by the output voltage.
