ESG Family Signal Generators 4 Hardkey and Softkey Reference This chapter describes each front panel hardkey and each softkey associated with the hardkey as well as the default value for each key. The chapter is organized alphabetically by front panel hardkey.
Hardkey and Softkey Reference AM ESG Family Signal Generators AM Pressing the front panel AM key reveals a menu of softkeys. These softkeys are described in this section in alphabetical order. AM Depth This softkey sets the amplitude modulation depth, in percent, for the AM Path 1 and AM Path 2 configurations. To change the value of the AM depth, press the softkey once. The current value for AM depth is displayed in the active entry area.
ESG Family Signal Generators Hardkey and Softkey Reference AM AM Off On This softkey enables the amplitude modulation for whichever AM path configuration you have selected, AM Path 1, AM Path 2, or AM Path WB, in the case of a digitally equipped model. Notice, however, that although you can enable amplitude modulation with this softkey, the RF carrier is modulated by the enabled modulation only when you have also set Mod On/Off to On.
Hardkey and Softkey Reference AM ESG Family Signal Generators The wideband AM selection (AM Path WB) eliminates the bandwidth limitations of the ALC loop thereby increasing the bandwidth beyond that of the standard amplitude modulation. Typical rates for wideband AM are listed in the technical specifications document. When you select AM Path WB in the AM menu, you must apply your modulating signal to the I input. The sensitivity is 0.5 V = 100% AM depth.
ESG Family Signal Generators Hardkey and Softkey Reference AM the external 1 source, the signal generator would turn off FM Path 1 and assign the external 1 source to your AM Path 2 configuration. Notice that for these purposes the external 1 AC-coupled source is the same as the external 1 DC-coupled source and the external 2 AC-coupled source is the same as the external 2 DC-coupled source.
Hardkey and Softkey Reference AM ESG Family Signal Generators AM Sweep Time Sets the sweep time for swept-sine amplitude modulation. The signal generator will vary the AM rate from the specified start rate to the stop rate in the time set with this softkey. Enter the desired sweep time using the up and down arrow keys, the front panel knob, or enter a value using the numeric keypad and press the sec or msec terminator softkey. The range of values allowed is 1 ms through 65.535 s.
ESG Family Signal Generators Hardkey and Softkey Reference AM AM Tone 2 Ampl Percent Of Peak For example, if the Tone 2 amplitude is 0%, then there would be no amplitude for Tone 2; all of the signal strength would be present in Tone 1. If AM Tone 2 Ampl Percent Of Peak is set to 50%, then Tone 2 and Tone 1 would have equal amplitudes, or half of the amplitude of both tones combined. Default Value: 50.
Hardkey and Softkey Reference AM ESG Family Signal Generators Dual-Sine Reveals a menu of choices for setting the dual-sine amplitude modulation parameters. In this menu you can set the AM rates for two separate tones. In addition, you can set the AM depth for AM Path 1 and AM Path 2 and also set a ratio of the tone 2 AM depth to the tone 1 AM depth.
ESG Family Signal Generators Hardkey and Softkey Reference AM Ext 2 AC-Coupled This softkey lets you input an external, AC-coupled, amplitude modulation signal to the EXT 2 INPUT connector. The modulation signal is tested for voltage and a display annunciator will report a high or low condition if the voltage is > ±3% of 1 Vpk. The external 2 input has multiple uses, but can be used for only one modulation at a time.
Hardkey and Softkey Reference AM ESG Family Signal Generators Internal This softkey lets you connect an internally-generated, calibrated signal to the AM modulator. The default state of the internal waveform generator is a 400 Hz sinewave with 0.1% depth. The internal source has multiple uses but can be used for only one modulation at a time.
ESG Family Signal Generators Hardkey and Softkey Reference AM Swept-Sine Pressing this softkey reveals a menu of choices for setting the swept-sine amplitude modulation parameters. In this menu you can set the start and stop AM rate and the sweep time. You can set the signal generator to a single, externally-triggered sweep on either a negative or positive TTL level or you can choose continuous sweep, triggered immediately.
Hardkey and Softkey Reference AM ESG Family Signal Generators Trigger Key This softkey is one of the choices in the AM Sweep Trigger menu. With Trigger Key selected, when you press the Trigger front panel key you immediately trigger a single sweep of swept-sine amplitude modulation. The Trigger key has autorepeat capability. Hold it down and you will repeatedly trigger sweeps until you release the key.
ESG Family Signal Generators Hardkey and Softkey Reference Ampl Ampl Pressing the front panel Ampl key reveals a menu of softkeys. These softkeys are described in this section in alphabetical order. ALC BW Normal Narrow Press this softkey to toggle between ALC normal and narrow bandwidth modes. The bandwidth is automatically set to narrow when external I/Q modulation is turned on, and automatically set to normal when I/Q modulation is turned off.
Hardkey and Softkey Reference Ampl ESG Family Signal Generators ALC Off On This softkey toggles the automatic leveling control (ALC) circuit off and on. The ALC is normally on. The RF output power of the signal generator is constantly monitored and controlled by the ALC circuit. Its purpose is to hold output power at its desired level in spite of drift due to temperature and time. There are some modulation conditions which the ALC circuit cannot handle properly which lead to output level errors.
ESG Family Signal Generators Hardkey and Softkey Reference Ampl Alt Ampl Delta (Option UNA Only) Press this softkey to set the delta value for the alternate amplitude function. The actual alternate amplitude is equal to the delta value plus the main RF output amplitude plus the amplitude offset value minus the amplitude reference value. Default Value: 0.
Hardkey and Softkey Reference Ampl ESG Family Signal Generators Ampl Offset Sets a value for amplitude offset. An amplitude offset changes the value shown in the amplitude area of the display but does not affect the output power. For example, if the current output power is 0 dBm and you enter an amplitude offset of −3 dBm, the output power will remain at 0 dBm but the display will show an amplitude of −3 dBm. This feature lets you simulates the power level at a test point beyond the RF OUTPUT connector.
ESG Family Signal Generators Hardkey and Softkey Reference Ampl Amplitude reference mode only changes the display; it does not change the RF output power. For example, if you set your RF output power to −20 dBm, set your reference value, and then turn amplitude reference mode on, your display shows your amplitude as 0 dB but your output power remains at −20 dBm. Default Value: Off Softkey Location: Ampl > Ampl Ref Off On Atten Hold Off On This softkey toggles the attenuator hold function on and off.
Hardkey and Softkey Reference Ampl ESG Family Signal Generators Power Search This softkey accesses a menu from which you can change power search parameters. Softkey Location: Ampl > ALC Off On > Power Search Power Search Manual Auto This softkey toggles between the auto and manual modes of power search mode. Power search is an internal calibration routine used to achieve calibrated output power when the ALC is off.
ESG Family Signal Generators Hardkey and Softkey Reference Amplitude Amplitude Press this front panel hardkey to change the RF output power. Amplitude becomes the active function and the current value is shown in the active entry area of the display. To enter a new value for amplitude, rotate the front panel knob until the desired value is displayed, use the up and down arrow keys, or enter the value using the numeric keypad and press the dBm, dBuV, dBuVemf, mV, uV, mVemf, or uVemf terminator softkey.
Hardkey and Softkey Reference Arrow Keys ESG Family Signal Generators Arrow Keys Use the up and down arrow keys to increase and decrease the value of a numeric parameter by the increment value. For example, when frequency is the active function, if the current frequency setting is 1 MHz and the increment value set is 1 kHz, pressing the up and down arrow keys will increase and decrease the 1 MHz frequency in 1 kHz steps.
ESG Family Signal Generators Hardkey and Softkey Reference Display Contrast Keys Display Contrast Keys You can adjust the contrast of the display by pressing the decrease contrast key or the increase contrast key . Pressing the decrease contrast key and holding it down causes the display background to gradually darken in comparison to the text on the display. The minimum contrast setting is not a completely black display. Some contrast between the background and the text will still be visible.
Hardkey and Softkey Reference FM ESG Family Signal Generators FM Pressing the front panel FM/ΦM key reveals a menu of softkeys. The softkeys for FM are described in this section in alphabetical order. For a description of the ΦM softkeys, refer to the “Phase Modulation” section in this chapter. Bus This softkey is one of the choices in the FM Sweep Trigger menu. With Bus selected, you use the GPIB to trigger single sweeps of swept-sine frequency modulation.
ESG Family Signal Generators Hardkey and Softkey Reference FM Ext This softkey is one of the choices in the FM Sweep Trigger menu. Choosing Ext allows you to trigger swept-sine frequency modulation using a signal applied to the TRIGGER IN rear panel connector. Set the polarity of the trigger signal using the Trigger In Polarity Neg Pos softkey.
Hardkey and Softkey Reference FM ESG Family Signal Generators Ext 2 AC-Coupled This softkey lets you input an external, AC-coupled, frequency modulation signal to the EXT 2 INPUT connector. The modulation signal is tested for voltage and a display annunciator will report a high or low condition if the voltage is > ±3% of 1 Vpk. The external 2 input has multiple uses but can be used for only one modulation at a time.
ESG Family Signal Generators Hardkey and Softkey Reference FM FM Dev Use this softkey to set the frequency modulation deviation for the FM Path 1 and FM Path 2 configurations. To change the value of the FM deviation, press the softkey once. The current value for FM deviation is displayed in the active entry area.
Hardkey and Softkey Reference FM ESG Family Signal Generators FM Off On Toggles the frequency modulation on or off for whichever FM path configuration (FM Path 1 or FM Path 2) you have selected. Notice, however that although you can turn on frequency modulation with this softkey, the RF carrier is modulated by the enabled modulation only when you have also set Mod On/Off to On. Whenever frequency modulation is enabled, the FM annunciator is turned on in the display.
