AC Voltage (VAC)
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 Reading........................................ 1100 counts
Accuracy
DC coupled:
DC to 60 Hz................................ ±(1.5 % +10 counts)
AC coupled, low frequencies:
50 Hz direct (1:1)....................... ±(2.1 % + 10 counts)
60 Hz direct (1:1)....................... ±(1.9 % + 10 counts)
With the 10:1 probe the low frequency roll off point will
be lowered to 2 Hz, which improves the AC accuracy
for low frequencies. When possible use DC coupling
for maximum accuracy.
AC or DC coupled, high frequencies:
60 Hz to 20 kHz......................... ±(2.5 % + 15 counts)
20 kHz to 1 MHz........................... ±(5 % + 20 counts)
1 MHz to 25 MHz ....................... ±(10 % + 20 counts)
For higher frequencies the instrument’s frequency roll
off starts affecting accuracy.
Normal Mode DC Rejection............................. >50 dB
All accuracies are valid if:
• The waveform amplitude is larger than one division
• At least 1.5 waveform period is on the screen
