Signal Generator Overview

Front Panel Display

1. Active Entry Area

The current active function is shown in this area. For example, if frequency is the active function, the current frequency setting will be displayed here. If the current active function has an increment value associated with it, that value is also displayed.

2. Frequency Area

The current frequency setting is shown in this portion of the display. Indicators are also displayed in this area when the frequency offset or multiplier is used, the frequency reference mode is turned on, or a source module is enabled.

3. Annunciators

The display annunciators show the status of some of the signal generator functions and indicate any error conditions. An annunciator position may be used by more than one function. This does not create a problem, because only one function that shares an annunciator position can be active at a time.

ΦM

This annunciator (Option UNT only) appears when phase modulation is on. If

 

frequency modulation is on, the FM annunciator replaces ΦM.

ALC OFF

This annunciator appears when the ALC circuit is disabled. A second annunciator,

 

UNLEVEL, appears in the same position if the ALC is enabled and cannot maintain

 

the output level.

AM

This annunciator (Option UNT only) appears when amplitude modulation is on.

ARMED

This annunciator appears when a sweep has been initiated and the signal

 

generator is waiting for the sweep trigger event.

ATTEN HOLD

This annunciator (E8267D or E8257D with Option 1E1 only) appears when the

 

attenuator hold function is on. When this function is on, the attenuator is held at

 

its current setting.

DIG BUS

This annunciator (Options 003/004 only) appears when the digital bus is active,

 

and the internal oven reference oscillator is not cold (OVEN COLD appears in this

 

same location).

ENVLP

This annunciator appears if a burst condition exists, such as when marker 2 is set

 

to enable RF blanking in the Dual ARB format.

ERR

This annunciator appears when an error message is in the error queue. This

 

annunciator does not turn off until you either view all the error messages or

 

cleared the error queue. To access error messages, press Utility > Error Info.

EXT

This annunciator appears when external leveling is on.

EXT1 LO/HI

This annunciator (Options UNT, UNU, or UNW only) appears as either EXT1 LO or

 

EXT1 HI, when the ac- coupled signal to the EXT 1 INPUT is < 0.97 Vp or

 

> 1.03 Vp.

EXT2 LO/HI

This annunciator (Options UNT, UNU, or UNW only) is displayed as either

 

EXT2 LO or EXT2 HI. This annunciator appears when the ac- coupled signal to the

 

EXT 2 INPUT is < 0.97 Vp or > 1.03 Vp.
