5.0 Mode descriptions

The following pages describe each operating mode of the 4070A. The meaning of each parameter that appears on the LCD display is described in detail.

5.1 Basic Sinewave (CW) Mode

Introduction

The Basic Sinewave (CW) mode generates a sinewave of fixed frequency and level. This mode could be entered by pressing the Sinewawe One touch mode selection key

NOTE: In this mode you can set the output frequency to 0 Hz and, by specifying an offset voltage, use the 4070A as a variable voltage source (with a 50O output impedance). Up to +/ - 70 mA can be drawn from the SIG Out output.

Sinewave Mode Parameters

The Sinewave mode has the following front panel display:

-10.0 dBm

Figure 5.1-1: Sinewave mode display

2

In this field enter the frequency of the sinusoid, from 0 Hz (DC) to 21.5 MHz in 0.01 Hz steps.

2. Level

In this field enter the output level, from 4 mVp -p to 10 Vp -p in 1 mV steps or from -44.0 dBm to +24.0 dBm in 0.1 dBm steps.

NOTE: The level specified is a 50O loaded level. This is the level of the signal, which will appear across a 50O load connected to the SIG Out connector. Into an open circuit, the output swing will be twice the value entered.

Offset

By pressing this key, you can enter an offset voltage for the output signal. For more information on output offsets refer to section 4.4.

Ext Gating Input

This TTL compatible input can be used to gate the output signal on or off. A logic high voltage on this jack (+3V to +10V) will turn off the output signal. A logic low voltage on this jack (0V to -10V) will leave the output signal on. For further information on the Ext Gating Input, refer to section 2.0.
