Characteristic Description
AC coupled, high frequencies
60 Hz to 20 kHz
±(2.5 % + 15 counts)
20kHzto1MHz
±(5 % + 20 counts)
1MHzto25MHz
±(10 % + 20 counts)
For higher frequencies, the frequency roll off of the instrument starts to affect accuracy.
Normal mode DC rejection
>50 dB
All accuracies are valid if:
The w aveform amplitude is larger than one division
At least 1.5 waveform periods are on the screen
AC+DC voltage (true R MS)
Maximum voltage
with 10:1 probe 1000 V
direct (1:1)
300 V
Maximum resolution
with 10:1 probe 1 mV
direct (1:1)
100 μV
Full scale measurement 1100 counts
Accuracy
DC to 60 Hz ±(1.5 % + 10 counts)
60 Hz to 20 kHz
±(2.5 % + 15 counts)
20 kHz to 1 MHz
±(5 % + 20 counts)
1MHzto25MHz
±(10 % + 20 counts)
For higher frequencies, the frequency roll off of the instrument starts to affect accuracy.
