7. Center Frequency <FREQ>

When

is pushed, the following function menu is displayed.

7.1

Setting with step keys ( [F1], [F2] )

1. When

is pushed, the center frequency decreases in the set step size.

2. When

is pushed, the center frequency increases in the set step size.

3. Setting step size:

When

is pushed, the step size is changed according to the following.

AUTO

100MHz

10MHz

1MHz

100kHz

20kHz

AUTO : The step size is 1/10 of the frequency span.

However, only for 500 kHz frequency span, the step size is set to 50 kHz.

If the frequency span is less than 500 kHz, the step size is set to 20 kHz.

AUTO is recommended for normal use.

7.2

Setting with encoder

1. By rotating

, the center frequency is changed in the set step size.

2. Setting step size:

When

is pushed, the step size is changed according to the following.

AUTO

100MHz

10MHz

1MHz

100kHz

20kHz

AUTO : The step size is 1/500 of the frequency span

However, if the frequency span is less than 5 MHz, the step size is set to 20 kHz.

AUTO is recommended for normal use.
