Optimizing Performance

Using an Output Offset, Reference, or Multiplier

All frequencies entered are interpreted as being relative to this reference frequency.

Amplitude: Press Amptd > More > Amptd Ref Set

The amplitude displays 0.00 dB, indicating that this is the RF output amplitude “zero level.”

All amplitudes entered are interpreted as being relative to this reference amplitude.

Examples

To set a new frequency or amplitude reference, turn the frequency reference off, and then follow the

steps above.

Setting a Frequency Multiplier

Using a frequency multiplier, the signal generator can display a frequency that is the multiple

(positive or negative) of the output value.

Displayed Value = multiplier value × output frequency

Output Frequency = displayed value ÷ multiplier value

To set a frequency multiplier:

1. Press Frequency > Freq Multiplier > multiplier value > x.

2. Set the desired frequency.

The display equals the output frequency times the multiplier value.

Comments

Reference: 50 MHz 50 MHz 2 GHz A reference value must be positive.

Entered (and displayed) Value: 2 MHz −2 MHz −1 GHz The entered value can be positive or negative.

Output Frequency: 52 MHz 48 MHz 1 GHz

The signal generator alerts you if the output frequency or

amplitude is out of range.
