Frequency Ratio:
Measurement is specified over the full signal range of each input.
Results Range:
10
–10
to 10
11
‘Auto’ Gate Time:
100 ms (or sufficient cycles on Channel 1 to make a valid measurement, whichever is longer)
LSD:
RMS Resolution:
To minimize relative phase measurement error, connect the higher frequency signal to Channel 1 when possible.
Peak Volts
Measurement is specified on Channels 1 for DC signals; or for AC signals of frequencies between 100 Hz and 30 MHz with peak-to-peak
amplitude greater than 100 mV. (The measurement will continue to operate up to 225 MHz, though results are for indication only.)
Results Range:
–5.1 V to +5.1 V
Resolution:
10 mV
Systematic Uncertainty for AC signals:
25 mV + 10% of V
for DC signals:
25 mV + 2% of V
Use of the input attenuator multiplies all voltage specifications (input range, results range, resolution and systematic uncertainty) by a
nominal factor of 10. For example with AC signals, the Systematic Uncertainty becomes: 250 mV + 10% of V.
