3. ARMING via an Ex ter nal BLANKING in put. When ARMING is set to
Blank ing ON, only sam ples taken when the rear panel Digi tal In put BNC is ac -
tive will be av er aged in the meas ure ment. The po lar ity of the rear panel Digi -
tal In put BNC sig nal can be set (high or low) us ing the
Sys tem|Rear
Panel|BNC| TTL LEVEL menu set ting. When ARMING is set to Blank ing OFF,
all sam ples are read.
4. In the SYSTEM|more|more| GRAPHICS menu, there are op tions for:
(a) CONNECT points. With this ON (de fault) the data points are con nected
with vec tors to re sem ble a real time trace. When OFF, the data points are dis -
played as data points only, with no con nect ing line. This can give a faster dis -
play up date, how ever, it may be con fus ing as near ver ti cal lines will have very
few points de fined within them.
(b) If Track ing min/max is se lected for the CHANNEL be ing used for the
PROFILE, it is pos si ble to con fig ure the track ing min/max to dis play the min
and max val ues for all the data BETWEEN THE CURSORS. This pro vides
easy ac cess to peak val ues within a time- window; for ex am ple, the top of a
pulse.
When set to SINGLE it is up dated EACH SWEEP and re flects the min and
max val ues only within that sweep.
When set to INFINITE, it main tains the min/max from the point it is started
un til it is re set, up dat ing the MAX if it sees a HIGHER meas ure ment within
the CURSOR win dow, and up dat ing the MIN read out if or when it sees a lower
value than that which it has al ready. This op tion, in the SYSTEM menu, is
only a pref er ences op tion and not the main con trol for the fea ture.
The con trol for the min/max re mains in the CHAN NEL menu
(CHANNEL|SETUP|-more-|MIN/MAX |RESET). The user should se lect the
way he wants to work and leave it. In most cases the SIN GLE (de fault) is the
most use ful as it pro vides a con tinu ously up dated read out of the min and max
points within the cur sor win dow. The IN FI NITE set ting is used when the re -
sults need to be col lated over a large number of sam ples. In or der to RE SET
the IN FI NITE con figu ra tion, use the CHAN NEL menu.
NOTE
In the trig gered modes, such as In ter nal A or B and Ex -
ter nal TTL, the SEN SOR|SETUP|Range HOLD fea -
ture can still be ap plied to re strict dy namic range if
re quired.
