Sharing a System
Often several users must share the receiver . When you nish your session it is useful to save
your setup so you can begin working quickly during your next session.
In this application you should:
1. Store one or more instrument state les to disc , as needed. If you have saved
many dierent instrument states you may want to store them all at once using the
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
INSTR STATE ALL softkey .
2. If you have performed one or more calibrations , store them to disc . If you used many
dierent calibrations , you may want to save them all at once using the
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
CAL SET ALL
softkey . Save an instrument state for each cal set. This will ensure that you can recall the
settings that are applicable for each calibration.
Calibrations are sensitive to ambient temperature and humidity , and therefore have a
limited life span. In addition, a cal set's life can be limited because of changes to the
system's components (including wear). Y ou can use \old" calibrations if you measure a
well-known device and compare the data to expected data. Y ou can then decide whether or
not the old calibration is still useful.
3. If using a special calibration kit, store the cal kit denition to disc too .
4. It is a good idea to save the hardware state to disc , especially if your receiver is controlling
more than one source . The hardware state saves all multiple source settings . The hardware
state also saves various HP-IB settings for external hardware . Y ou can skip this if the
hardware setup rarely or never changes .
5. If using a user-generated delay table , store it to disc .
6. If you created special graphic elements , store them to disc .
Saving Everything
If you use a large number of states , cal sets , memories , and so on, you may nd that storing
using
N
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Machine Dump is easier . This takes longer than saving one or two individual types
of data, and takes up more disc space . However , this may be the best method in complex
situations .
When you load a Machine Dump from disc , the contents of applicable internal registers are
replaced with the data from the machine dump le .
A Machine Dump le does not automatically save the current measurement settings. Before
saving a Machine Dump , always save the current measurement setup to save register 8. If you
do this , the instrument will return to a known setup when you load the Machine Dump le .
Viewing or Plotting Old Data
If you know you want to plot, analyze , or view data at a later date , store the Raw , \Data," or
\F ormatted" data to disc .
