Characteristics Performance Requirements
STORE Mode Dynamic Range 10.24 divisions.8
STORE Mode Resolution
Acquisition Record Length
1024 or 4096 data points.8
Single Waveform Acquisition Display 1024 data points (100 data points per division across the graticule
area).8
CHOP or ALT Acquisition Display 512 data points (50 data points per division across the graticule
area).8
Horizontal POSITION Control Range
(NON STORE)
Start of the 10th division will position past the center vertical grat­
icule line; 100th division in X I0 magnified.
Horizontal Variable Sweep Control Range
NON STORE Continuously variable between calibrated settings of the SEC/DIV
switch. Extends the A and the B Sweep speeds by at least a fac­
tor of 2.5 times over the calibrated SEC/DIV settings.
STORE
Horizontal Variable Sweep has no affect on the STORE Mode
time base. Rotating the Variable SEC/DIV control out of the CAL
detent position horizontally compresses a 4K point acquisition
record to 1K points in length, so that the whole record length can
be viewed on screen. Screen readout is altered accordingly.
Displayed Trace Length
NON STORE
Greater than 10 divisions.
STORE 10.24 divisions 8
Delay Time
0.5
ms
per division to 0.5 sec per division
(A Sweep)
Delay POSITION Range
Less than (0.5 div + 300 ns) to greater than 10 divisions.
Delay Time is functional, but not calibrated, at A Sweep speeds
faster than 0.5
ms
per division.
NON STORE Delay Jitter One part or less in 5,000 (0.02%) of the maximum available delay
time.
Delay Time Differential Measurement Accuracy
(Runs After Delay only)
+ 15*0 to +35*C
± 1 % of reading, ± 0.3% of full scale (10 div).
0°C to +50-C
±2% of reading, ±0.3% of full scale (10 div).8
Exclude delayed operation when the A and B SEC/DIV knobs are
locked together at any sweep speed or when the A SEC/DIV
switch is faster than 0.5
ms
per division. Accuracy applies over the
B DELAY TIME POSITION control range.
