Signal Generator Overview

Front Panel

12. EXT 2 INPUT

This female BNC input connector (E8257C and E8267C only) accepts a ±1Vp signal for AM, FM, and Φ M. With AM, FM, or Φ M, ±1 Vp produces the indicated deviation or depth. When ac-coupled inputs are selected for AM, FM, or Φ M and the peak input voltage differs from 1Vp by more than 3%, the HI/LO annunciators light on the display. The input impedance is selectable as either 50Ω or 600Ω and damage levels are 5 Vrms and 10 Vp. On signal generators with Option 1EM, this input is relocated to the rear panel.

13. LF OUTPUT

This female BNC output connector (E8257C and E8267C only) outputs modulation signals generated by the low frequency (LF) source function generator. This output is capable of driving 3Vp (nominal) into a 50Ω load. On signal generators with Option 1EM, this output is relocated to the rear panel.

14. Mod On/Off

This hardkey (E8257C and E8267C only) enables or disables all active modulation formats (AM, FM, Φ M, Pulse, or I/Q) applied to the output carrier signal available through the RF Output connector. This hardkey does not set up or activate an AM, FM, Φ M, Pulse, or I/Q format; each modulation format must still be set up and activated (for example, AM > AM On) or nothing is applied to the output carrier signal when the Mod On/Off hardkey is enabled. The MOD ON/OFF annunciator, which is always present on the display, indicates whether active modulation formats have been enabled or disabled with the Mod On/Off hardkey.

15. ALC INPUT

This female BNC input connector is used for negative external detector leveling. This connector accepts an input of −0.2 mV to −0.5V. The nominal input impedance is 120 kΩ and the damage level is ±15V. On signal generators with Option 1EM, this input is relocated to the rear panel.

16. RF On/Off

Pressing this hardkey toggles the operating state of the RF signal present at the RF OUTPUT connector.

Although you can set up and enable various frequency, power, and modulation states, the RF and microwave output signal is not present at the RF OUTPUT until RF On/Off is set to On. An annunciator is always visible

in the display to indicate whether the RF is turned on or off.

17. Numeric Keypad

The numeric keypad consists of the 0 through 9 hardkeys, a decimal point hardkey, and a backspace hardkey

( ). The backspace hardkey enables you to backspace or alternate between a positive and a negative value. When specifying a negative numeric value, the negative sign must be entered prior to entering the numeric value.
