Operating Instructions
1720/1721
2–7
switch can be used independently, even though the instrument is in the AUX-
ILIARY mode.
REF switching allows the 1730-Series to select either INT or EXT reference. It
will not switch to TEST when the 1730-Series is switched to CAL. Reference
will automatically be switched to EXT if the INPUT is switched to BOTH (from
either waveform monitor or vectorscope). If the 1720/1721 REF switch is in
TEST, the 1730-Series switching will not take it out of that mode.
The 1720/1721 normal operation is full field. When it is used in AUXILIARY,
the 1730-Series LINE SELECT switching controls the display on the vector-
scope. It should be noted that the 1720/1721 has no line selection capability
when it is not connected to a 1730-Series Waveform Monitor.
The current state of the front panel can be stored, in AUXILIARY mode, by
executing the 1730-Series STORE command. When the 1730-Series STORE
button is pushed, the 1720/1721 front-panel indicators will blink to acknowledge
that the command was received. The current front-panel configuration will now
be stored in the 1720/1721 NOVRAM as soon as one of the 1730-Series
RECALL buttons is pushed.
NOTE. Use caution to retain desired 1730-Series stored configurations. Read the
STORE and RECALL SETUP instructions in Section 2 of the 1730-Series
Instruction manual before proceeding.
Note that the indicators also blink when the 1720/1721 is not in AUXILIARY;
however, the front-panel configuration is not stored and the 1720/1721 front
panel will not change when that stored function (on the 1730-Series) is recalled.
When the 1720/1721 is in the AUXILIARY mode and contains stored front-pan-
el configurations, it reacts to 1730-Series RECALLs. When one of these
RECALL buttons is pushed, the stored front-panel configurations of both
instruments will be recalled. All front-panel controls remain active during
AUXILIARY mode, and can be used to make changes in current front-panel
configurations.
During AUXILIARY operation, the 1720/1721 front-panel indicators continue to
accurately display its current status.
