Specifications:

1-Input: -Input A: •Input Impedance: 1MW//20pF (AC coupled) •Frequency Range: <3Hz to >125MHz •Sensitivity: Sinewave - 15mVrms 10Hz-125MHz -Input B: •Input Impedance: 50W (AC coupled) •Frequency Range: <80MHz to >3000MHz •Sensitivity: Sinewave - 15mVrms 80MHz-2GHz, 50mVrms to 3GHz -Maximum Input Voltage: Input A and Input B: 30Vdc; 30Vrms 50Hz/60Hz reducing to 1Vrms above 1MHz 2-Measurements: -Frequency (Range A): •Frequency Range: 3Hz to 125MHz •Resolution: 10-7Hz to 100Hz (see Note) -Frequency (Range B): •Frequency Range: 80MHz to >3000MHz •Resolution: 1Hz to 10kHz (see Note) -Period (Range A only): •Period Range: 8ns to 330ms •Resolution: 10-7ns to 1us (see Note) -Measurement Time: Selectable as 10s, 1s or 0.1s. (Note that for the 0.1s setting the effective measurement time is 0.3 seconds). -Resolution: The displayed resolution depends upon the measurement time and the input frequency. Eight digits (or nine using an overflow indication) are displayed for a 10s measurement time. Seven or eight digits are displayed for a 1s measurement time, and six or seven digits for 0.1s depending upon the input frequency. Usable resolution may be further reduced by noise, particularly at low frequencies. -Accuracy: Measurement accuracy is the sum of the timebase accuracy and measurement resolution plus one count.
