Signal Generator Overview

Front Panel

12. EXT 2 INPUT

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

13. LF OUTPUT

This female BNC output connector (functional only with Option UNT) outputs modulation signals generated by the low frequency (LF) source function generator. This output is capable of driving

3Vp (nominal) into a 50 ohm load. On signal generators with Option 1EM, this connector is located on the rear panel.

14. Mod On/Off

This hardkey (E8267D and E8257D with Options UNT, UNU, or UNW and E8267D only) enables or disables all active modulation formats (AM, FM, ΦM, 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, ΦM, 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 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 −0.5 V. The nominal input impedance is 120 kohms and the damage level is ±15 V. On signal generators with Option 1EM, this connector is located on 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 connector until RF On/Off is set to On. The RF On/Off 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.
