Choice of Capabilities

The 4410B model is a 10MHz generator, which

combines sine, triangle, square and DC capabi-

lities in one small unit. All these waveforms are

available over a very broad frequency and

amplitude range with a choice of sweep and

modulation modes. Variable symmetry from

10 % to 90 % offers the possibility to generate

ramps and pulse waveforms.

The LCD displays (backlighted) 2 parameters at

the same time.

Variable Amplitude and Offset

The 4410 B generator separate amplitude

and offset controls allow you to super-

impose a DC component on the AC output

waveform. The output level can be conti-

nuously adjusted over a 20 dB range and

attenuated by 20 dB or 40 dB fixed atte-

nuator.

Sweep Capabilities

The sweep mode can be internally or exter-

nally controlled. Sweep start and stop fre-

quencies are independently adjustable.

Linear or log. sweep capabilities.

SEFRAM Generators series

The SEFRAM generators series are your solution for studying low-and hight frequency electrical and electronic phenomena and general physical

parameters. Please find in the following selection guide their specifications and choose the model that meets your needs

Modulation

The output waveform can be amplitude or

frequency modulated by an internal (1KHz)or

external signal. The modulation level is ajdus-

table 0 to 100%.

Frequency Counter

A built-in digital counter that display the instru-

ment frequency allows precise settings. An

additional converter enables the reading of very

low frequencies with high resolution. This 6

digits autoranging counter can be used to mea-

sure external signals.

WAVEFORMS

Sine, square, triangle and DC.

OPERATING MODES

Symmetry : 10% to 90%, up to 1 MHz

Sweep : The output waveform can be linear internally swept over

100 : 1 range. The sweep start and stop freq. can be independently

adjusted and the sweep rate can be set from 20 ms to 10s.

Modulation : The output can be AM and FM modulated by an

internal or external signal. The internal modulation is a 1 KHz

sinewave.

FREQUENCY CHARACTERISTICS

Range : 0.01 Hz to 10 MHz in 8 overlapping ranges. Each range

capable of over 100 : 1 frequency change.

Control : The range is selected by up and down keys; frequency

within the range is set with a multiturn control.

Display : Up to 4 digits (1100 counts) with backlight LCD, range

units (MHz, KHz, Hz, and mHz) and decimal point.

Display accuracy is 0.01 % of reading ± 1 LSB from 100 Hz to 10 MHz and 3%

from 0,01 Hz to 99

Hz .

OUTPUT CHARACTERISTICS

Amplitude Range : Up to 10 Vp-p into 50 Ω(20 vp-p into open circuit).

Amplitude Controle : >20 dB continously variable.

Amplitude Attenuator : 2 independant attenuators with a

±2

accuracy

Amplitude Flatness :

± 0,5 dB to 1 MHz

± 2 dB to 10 MHz

Offset range :

Variable up to ± 10 V. Absolute peak amplitude plus offset

limited to 10 V (± 5 V into 50

Ω).

Output impedance : 50 Ω

Output protection :

The generator main output is non-destructively pro-

tected against short circuit to ground or to any voltage practically available

in electronic laboratories.

WAVEFORM CHARASTERISTIC

Sine Distorsion :

< 1 %THD, 10 Hz to 100 KHz.

< 25 dBc above 100 KHz

Triangle Linearity :

> 98 % to 100 KHz.

Square Transition Times :

< 22 ns 10 % à 90 % at full output amplitude

terminated into 50

< 5 % of p-p amplitude ± 50 mV

INPUTS AND OUTPUTS

• Sync, Out :

TTL levels square wave with a 50

Ω

impedance

Can drive a

minimum of 20 TTL loads.

• Sweep In-Out :

0-5 V input for a up to 100 : 1 frequency change. In

the sweep mode, the sweep voltage is available at this output.

Output impedance : 600

Ω

Input impedence : 10

Ω

• Mode In-Out :

The internal 1 KHz sine-wave is available for external

synchronisation. The signal amplitude is 2 Vp-p and 600

Ω

output impe-

dance.

In EXT modulation mode, a signal applied to this input will modulate the

output signal. A 2 Vp-p signal is required for a 100 % AM modulation. The

input impedance is 10
