Count In
The AM/COUNT IN socket is set to external frequency measurement when EXT COUNT is
selected.
Input Impedance:
1MΩ//20pF.
Input Sensitivity:
50mVrms (sinewave).
Maximum Allowable
Input Voltage:
30Vdc/30V
rms to 50Hz/60Hz with respect to ground , reducing to
1Vrms above 1MHz.
DISPLAY FUNCTIONS
The LCD shows generator frequency setting at a resolution of 4 digits simultaneously with output
amplitude/offset, together with various status annunciators. Alternatively, the generator
frequency setting can be displayed independently of amplitude/offset to a resolution of 6 digits.
The LCD also functions as the external frequency measurement display with up to 7 digits of
resolution.
Internal Measurement Accuracy
Amplitude: Display shows peak-to-peak amplitude or rms value. Display corrected
for attenuator setting and waveform type. 3-digit resolution, accuracy
typically ±5% of range full scale.
DC Offset: 3-digit resolution; accuracy typically ±2% of setting ±1 digit. Display
corrected for attenuator setting.
External Frequency Measurement
Frequency Range:
3Hz to >120MHz.
Frequency Resolutuion:
Up to 7 digits displayed.
Input Sensitivity:
Better than 50mVrms (sinewave).
Measurement Time:
Automatic.
Accuracy:
±1 digit ± timebase accuracy.
Timebase Accuracy: <±5ppm initial error; <± 5 ppm/year ageing rate; typically less than
1ppm/°C.
