ALTERNATE/DELAYED SWEEP
Top of the line in Leader's instruments, Model LS 8106A offers
speed and operating shortcuts found in very few modern scopes.
Examples include Auto Setup in which a single touch automatically
sets both V sensitivity and timebase for instant, optimum waveform
display. Another great convenience is a continuous on-screen readout
of the operator's choice of frequency or period and Vp-p or DC
level for signals handled in CH1. Solid state switching in the
vertical attenuators also eliminates switching noise and ensures
long-term reliability. To aid in documentation, on-screen readouts
register the status of V and timebase scale factors in use as well
as coupling, uncal warning, INVert, ADD, use of MAG, X-Y operation
and delay time. These readouts are augmented by precision cursors
to make quick work of measuring voltage and time for parts of the
waveform as well as frequency, % of presets for both voltage level
and time. For example, the latter reads out phase angle in degrees
when the timebase is taken out of CAL preset to make a full cycle
span 5 divisions. Other features include 3-channel operation with
sync selected from all. A maximum of 8 traces can be shown (main
and delayed timebases for CH1, CH2, CH3 and ADD (or subtract).
SYNCHRONIZATION
Delayed sweep allows a segment of the Main (A) sweep to be expanded
using a shorter B sweep that is placed in position with the DLY
(delay) control. The time span of the B sweep is shown highlighted
on the A trace and the B trace can be observed by itself. Alternate
sweep shows both the highlighted A trace and the B trace simultaneously.
With 3 channels and alternate sweep in use, a total of 6 traces
can be set up (8 traces if CH1, CH2 sum or difference is also selected).
Delay time for the B trace appears on-screen in the Model 8105.
EXTRAS
The sync reference may be sourced from channel 1, 2, 3 or the power
LINE. But with the SOURCE set to VERT the selection is automatic
and depends upon the channel(s) in use. Sync MODE settings include
AUTO, NORM, FIX and SINGLE. The FIXed mode tracks signal amplitude
to keep the trigger point within the p-p span and maintain hold
despite level changes. Coupling choices include AC, HF REJ, DC,
TV-V and TV-H. The last two employ dedicated sync separators to
ensure rock-solid video waveforms. EXTRAS
Features worthy of consideration include X-Y operation needed for
Lissajous patterns of stereo signals or setup of raster displays,
triggered-delayed sweep where the B trace waits for the next trigger
after the delay time. In SINGLE SWEEP the trace is armed and ready
to catch random or one-time events. CH1 output (rear panel) allows
the CH1 amplifier to be used as a high-gain, calibrated preamp.
