ESG Family Signal Generators Getting Started

Creating an FM Signal

This procedure will show you how to conﬁgure the signal generator to output a frequency-modulated signal with the following characteristics:

• carrier frequency set to 104.9 MHz

• power level set to 0 dBm

• FM deviation set to 75 kHz

• FM rate set to 10 kHz

Setting the Carrier Frequency

1. Press Preset. This sets the signal generator to its factory-deﬁned instrument

state.

2. Press Frequency. Frequency becomes the active function and the preset value for frequency is displayed in the active entry area.

3. Enter 104.9 using the numeric

keypad and press the MHz softkey.

The new carrier frequency (104.900 000 00 MHz) is shown in both the FREQUENCY area and the active entry area of the display.

Setting the Power Level

1. Press Amplitude. Amplitude becomes the active function and the preset value for

amplitude is displayed in the active entry area.

2. Enter 0 using the numeric

keypad and press the dBm softkey.

Quick Start Guide 1-3

The new power level (0.00 dBm) is shown in both the AMPLITUDE area and the active entry area of the display.

Getting Started ESG Family Signal Generators Creating an FM Signal

Setting the FM Deviation

1. Press FM/φM. The ﬁrst level menu of FM softkeys is displayed.

2. Press the FM Dev softkey. FM deviation becomes the active function and the preset value

for FM deviation is displayed in the active entry area.

3. Enter 75 using the numeric keypad and press the kHz softkey.

The new FM deviation is displayed below the FM Dev softkey. You should see 75.0000 kHz in the second line of the softkey label.

Setting the FM Rate

1. Press the FM Rate softkey. FM rate becomesthe activefunction andthe presetvaluefor FM

rate is displayed in the active entry area.

2. Enter 10 using the numeric keypad and press the kHz softkey.

The new FM rate is displayed below the FM Rate softkey. You should see 10.0000 kHz in the second line of the softkey label.

Turning On Frequency Modulation

The signal generator is now conﬁgured to output a 0 dBm, frequency-modulated carrier at

104.9 MHz with the FM deviation set to 75 kHz and the FM rate set to 10 kHz. The shape of the waveform is a sinewave.

NOTE Sine is the default selection forthe FM Waveform softkey. Press More (1 of 2) to see

the softkey.

Follow these remaining steps to output the frequency-modulated signal:

1. Press the FM Off On softkey. FM toggles from Off toOn. Notice, also, that theFM display

annunciator is turned on, indicating that you have enabled frequency modulation.

2. Press RF On/Off. Notice that the display annunciator changes fromRF OFF to

RF ON. The modulated signal is now available at the

RF OUTPUT connector.

Creating a Step Sweep and a List Sweep

This section will show you two ways to set up the signal generator to sweep a deﬁned set of points. You will create a ten-point step sweep with the settings listed below, then use these points as the basis for a new list sweep.

• frequency range from 525 MHz to 600 MHz

• power level from −20 dBm to 0 dBm

• dwell time 500 ms at each point

Conﬁguring a Step Sweep

1. Press Preset. This sets the signal generator to its factory-deﬁned instrument

state.

2. Press Sweep/List. The ﬁrst level of sweep softkeys is displayed.

3. Press the Sweep Type List Step

softkey.

4. Press the Conﬁgure Step Sweep softkey.

5. Press the Freq Start softkey. Enter 525 using the numeric keypad and press the MHz softkey.

6. Press the Freq Stop softkey. Enter 600 using the numeric keypad and press the MHz softkey.

7. Press the Ampl Start softkey. Enter −20 using the numeric keypad and press the dBm softkey.

This toggles the Sweep Type List Step softkey from List to

Step.

Another menu is displayed with softkeys that you will use to create the sweep points.

This setsthe new start frequencyforthe stepsweep to525 MHz.

This sets the new stop frequency for the step sweep to 600 MHz.

This sets the power level for the start of the step sweep to

−20 dBm.

keypad and press the dBm softkey.

9. Press the # Points softkey.

This sets the number of points in the step sweep.

Enter 10 by rotating the front panel knob until the number 10 is displayed.

10. Press the Step Dwell softkey.

This sets the dwell time for each point in the step sweep.

Enter 500 using the numeric keypad and pressing the msec softkey.

Turning On Continuous Step Sweep

1. Press Return. This moves the softkey menu up one level.

2. Press the Sweep softkey. Another menu is displayed, showing you choices for sweeping

either the frequency, amplitude,or frequency andamplitude data.

3. Press the Freq & Ampl softkey. Selectingthis softkeyreturns you tothe previous menuandturns

the sweep function on.

4. Press the

Sweep Repeat Single Cont

softkey.

This toggles the Sweep Repeat Single Cont softkey from

Single to Cont (Continuous). Notice that theSWEEP display

annunciator is turned on, indicating that the signal generator is sweeping.

5. Press RF On/Off. Notice that the display annunciator changes fromRF OFF to

RF ON. The swept RF signal is now available at the

RF OUTPUT connector.

Creating a Step Sweep and a List Sweep

Conﬁguring a List Sweep Using Step Sweep Data

1. Press the Sweep Type List Step

softkey.

2. Press the Conﬁgure List Sweep softkey.

This toggles the Sweep Type List Step softkey from Step to

List.

Another menu is displayed with softkeys that you will use to create the sweep points. Notice that the display shows the current list data. (When no list has been previously created, the default is one point set to the signal generator’s maximum frequency, −135dBm, with a dwell time of 2 ms.)

3. Press the following softkeys:

More (1 of 2) > Load List From Step Sweep > Conﬁrm Load From Step Sweep.

The points you deﬁned in the step sweep are automatically loaded into the list.

4. Press the More (2 of 2) softkey. This softkey menu along with the numeric keypad, arrow keys,

and front panel knob can be used to edit the sweep points in the list. For more information about editing sweep points, refer to Chapter 2, “Using Functions,” of the ESG Family Signal Generators User’s Guide.
