Instructions

Horizontal systems - analog channel
Deskew range +/- 100 ns with 1ns resolution
Horizontal zoom Horizontally expand or compress a live or a stopped waveform
Timebase accuracy 50 ppm
Seconds\Division range 2 ns/div to 100 sec/div in a 1-2-4 sequence.
Signal acquisition system characteristics
No of input channels Two
Input coupling DC or AC
AC coupling connects a capacitor in series with the input circuitry. The DC input
impedance becomes very high, since capacitance is in series with all paths to
ground.
Input impedance, DC coupled 1 MΩ, ±2 %
Input capacitance, DC coupled 14pF ± 2pF
Maximum input voltage A300 V RMS, CAT II; derate above 4 MHz at 20 dB per decade to 200 MHz
Number of digitized bits 8 bits
Sensitivity range 1 mV/div to 10V/div in 1-2-5 sequence with probe attenuation set to 1X.
Probe scale factors 1X, 10X, 20X, 50X, 100X, 500X, 1000X voltage attenuation.
5, 1, 500 m, 200 m, 100 m, 20 m, 10 m, 1 m V/A current scale factor.
This adjusts the display scale factor of the instrument to accommodate various probe
types.
Accuracy of the probe used must be added to the accuracy specifications of
instrument.
No automatic probe interface is provided, so you must verify that the settings match
the probe characteristics. The probe check function allows setting of the proper
attenuation for voltage probes.
Acquisition modes Sample, Peak detect, Average
Retained front panel settings Front panel settings are retained when the instrument power is turned off and on with
the power switch. The settings are retained when the line power is turned off and on.
The instrument periodically saves front panel settings after settings are changed.
There is a delay of three seconds after the last change and before the storage of the
settings in memory.
Math modes Channel 1 – Channel 2
Channel 2 – Channel 1
Channel 1 + Channel 2
