4.4.10 Frequency Measurement via Input2 (10 Hz to 10 MHz)
To measure frequencies between 10 Hz and 10 MHz, select the Input2 connector and an impedance of 1M Ω.
To measure frequencies between 10M Hz and 1 GHz, select the Input2 connector and an impedance of 50 Ω. For more
details, see 4.4.9.
(1) Connecting the input signal
Connect the signal to measure to the Input2 connector on the front panel.
Note:
Do not connect a signal of 10 Vrms (at 1M Ω)/2Vrms (at 50 Ω) or higher to the Input2 connector.
(2) Setup
1) Press the [Preset] key to preset this unit.
2) Set the input channel to Input2.
Press the [Input] key to display the input parameter setup screen. Enclosing the menu F1 in a thick frame with the
[<] and [>] keys and then pressing the [Enter] key select Input2.
3) Select an input impedance.
Enclosing the menu F2 in a thick frame with the [<] and [>] keys and then pressing the [Enter] key select 1M Ω.
4) Switch between input attenuators.
When the input level of the signal to measure is low, turn off the attenuator. Enclosing the menu F3 in a thick
frame with the [<] and [>] keys and then pressing the [Enter] key select Off.
5) Pressing the [Return to Meas] key displays the normal measurement screen.
6) Using the [<] and [>] keys, set a desired frequency measurement resolution.
7) Using the [ ] and [ ] keys, set a desired sample rate.
