详细参数(pdf文件)

the hitachi portable read-out oscilloscope provides
measurement reliability and ease of operation by employing a
microprocessor. the major features are:

(1) measurement information display
the measurement information including the sweep speed,
the delay time, the uncal display, and the voltage
sensitivity of the vertical axis (cursor readout type only)
is alphanumerically displayed on the crt.
since troublesome setting operation procedures are elimi-
nated, an operator can concentrate on the displayed data
for measurement.

(2) measurement value display (cursor readout type only)
the distance between the two cursors displayed can read
out the following;
△v: voltage between the reference cursor and the
delta cursor
△t: time between the reference cursor and the delta
cursor
1/△t: reciprocal of the time
the displayed data eliminates troublesome and time con-
sunling calculation procedures. moreover, miscalculation
of the scales is completely avoided.
(3) automatic time base range setting

at a press of the auto button, an optimum time base range is automatically set. (a signal period from 1.6 to 4 cycles approx. is displayed.)
the time base range is automatically changed to a corresponding change in input signal period.

(4) frequency counter (cursor readout type only) the a trig signal frequency can be measured.

(5) trigger lock

since complicated pulse train waveforms are hard to trigger on, performing the trigger lock function enables sweep independent triggering.
the “sweep time plus holdoff time” is fixed and a stable trigger is obtained at any time range.

(6) channel input quad channel input (v-1585, v-1085 on

besides ch1 and ch2, ch3 and ch4 provided with 0.5 v/ div and 0.1 v/div range se-lection capabilities are provided for easy digital signal measurement.

(7) bandwidth
v-1585, v-1085, v-1565, v-1065a, v-1560, v-1060
dc-100mhz (2mv/div: dc-20mhz)

v-695, v-665a, v-660
dc-60mhz (2mv/div: dc-10mhz)

(8) high sensitivity
high sensitivity of 2 mv/div is provided.

(9) internal graticule
internal graticule lines eliminate parallax-viewing error between the trace and the graticule lines.

(10) delayed sweep
with delayed sweep, a portion of the signal can be magnified for more accurate measurement and time comparison. the delay time is digitally displayed on the crt.

(11)auto trigger level
auto measuring of trigger level is employed, so that trigger level range is matched to the trigger signal for maximum trigger sensitivity and stability.

(12) tv triggering
exclusive tv sync separator circuit technology provides stable tv signal measurements on fields, frames and lines.
