Characteristic Description
√ Sine and Ramp Frequency
Accuracy
130 ppm (frequency
≤ 10 kHz); 50 ppm (frequency > 10 kHz)
√ Square and Pulse Frequency
Accuracy
130 ppm (frequency ≤ 10 kHz); 50 ppm (frequency > 10 kHz)
√ Signal Amplitude Accuracy
+/–[ (1.5% of peak-to-peak amplitude setting) + (1.5% of absolute DC offset setting)
+ 1 mV ] (frequency = 1 kHz)
√ DC Offset Accuracy
+/-[ (1.5% of absolute offset setting) + 1 mV ]
Add 3 mV of uncertainty per 10 °C change from 25 °C ambient
Table 3: DVM/Counter
Characteristic Description
√ Voltage Accuracy
DC: +/- (2 mV + [((( 4 * (Vertical Scale Voltage)) / (Absolute Input Voltage)) + 1)% of
Absolute Input Voltage] + (0.5% of Absolute Offset Voltage))
AC: ±2% (40 Hz to 1 kHz)
AC: +/-2% (20 Hz to 10 kHz) (typical)
For AC measurements, the input channel vertical settings must allow the V
pp
input
signal to cover between 4 and 8 divisions.
√ Frequency Accuracy
10 ppm
√ Frequency Counter Maximum
Input Frequency
100 MHz for 100 MHz models.
150 MHz for all other models.

Characteristic Description
√ Auxiliary Output (Aux Out)
Selectable Output: Main Trigger, Event, or AFG
Main Trigger: HIGH to LOW transition indicates the trigger occurred.
Event Out: The instrument will output a negative edge during a speci
fi ed trigger event
in a test application.
A falling edge occurs when there is a speci
fi ed event in a test application (i.e. the
waveform crosses the violation threshold in the limit / mask test application).
A rising edge occurs when the trigger system begins waiting for the next test
application event.
AFG: The trigger output signal from the AFG.
