326 SPECIFICATION
Secti n 1—326 (SIM 300500-up)
Intr ducti n
The SONY/TEKTRONIX 326 Oscilloscope is a solid-
state portable instrument that combines small size and li ht
wei ht with the ability to make precision waveform
measurements.
A dual-trace DC to 10 MHz vertical system provides
calibrated deflection factors from 0.01 Volt/Div to
10 Volts/Div (0.001 Volt/Div minimum with reduced
frequency response).
The tri er circuit provides stable tri erin over the full
vertical bandwidth. A 300 ns delay line in the vertical
system allows the operator to view the portion of the
waveform on which tri erin occurs.
The horizontal deflection system provides calibrated
sweep rates from 1 jUs/Div to 1 s/Div. A 10X ma nifier
extends the sweep rate to 0.1 jiis/Div.
The 326 can be operated from internal battery, an
external DC source, or from the AC line (with battery
char er attached).
The followin electrical characteristics apply over an
ambient temperature ran e of +20°C to +30° C (+68°F to
+86°F). Warmup time for the accuracies iven is approxi
mately 10 seconds.
CHARACTERISTICS
VERTICAL AMPLIFIER
Deflection Factor
Ran es: 10 mV/Div to lOV/Div in XI Gain and
1 mV/Div to 1 V/Div in X10 Gain. 10 steps in a 1-2-5
sequence. Accuracy within 3% over the calibrated ran e.
Variable: Variable between calibrated deflection factor
settin s. Extends the hi hest deflection factor to at least
25 V/Div.
Attenuator Compensation: +1%, —1%, or less, 0°C to
+55°C (+32°F to +131°F). +2%, -2%, or less, -15°C to
0°C (+5°Fto+32°F).
Frequency Response
Bandwidth (Variable Volts/Div at CAL, 4 division
reference) direct coupled: IX Gain, DC to at least
10 MHz (upper —3dB point) with the P6049A Probe.
Capacitively coupled, 4 division reference: from 10 Hz
or less (lower —3 dB point) at all deflection factors. 1 Hz
or less with the P6049A Probe.
Step Response (risetime), 4 division step input: 36 ns or
less in XI Gain and 72 ns or less with X10 Gain.
Aberrations: +2.5%, —2.5% with total of 4% or less in all
modes except ADD ALG. +3%, —3% with total of 6% or
less in ADD ALG Mode.
Input
Maximum Volta e: 500 volts direct coupled (DC + peak
AC) or capacitively coupled DC volta e.
Resistance: 1 M£2, within 2%, direct and 10 M£2, within
2%, with the P6049A Probe.
Capacitance: 47 pF within 4 pF direct and 13.5 pF or
less with the P6049A Probe.
Amplifier
Linear dynamic ran e in Added Mode: Equal to or
reater than 8 times the Volts/Div settin for 10%
distortion.
Common-Mode Rejection: At least 20:1 at 2 MHz for a
common-mode si nal of 80 mV peak-to-peak, Volts/Div
set at 10 mV and CH 2 set for maximum CMRR at
50 kHz and 10 mV.
DC Drift
With Time (short term): 0.2 div or less durin any
minute within the first hour after a 10 second
warmup (with temperature and line volta e constant).
