Rate (typical 1 dB bandwidth)

ALC on 1 kHz to 80 MHz

ALC off DC to 80 MHz

External 1 input

Sensitivity 0.5 V = 100%

Input impedance 50 Ω (nominal)

Modulation types AM, FM, and ΦM

Input impedance 50 or 600 Ω (nominal), switched

High/low indicator

(100 Hz to 10 MHz BW, ac coupled inputs only) Activated when input level error exceeds 3% (nominal)

All modulation types may be simultaneously enabled except: FM with ΦM, linear AM with

exponential AM, and Wideband AM with I/Q. AM, FM, and ΦM can sum simultaneous inputs

from any two sources (Ext1, Ext2, internal1, or internal2) Any given source (Ext1, Ext2, internal1,

or internal2) may be routed to only one activated modulation type.

Dual function generators provides two independent signals (internal1 and internal2) for use with

AM, FM, ΦM, or LF Out.

Waveforms Sine, square, positive ramp, negative ramp, triangle,

Gaussian noise, uniform noise, swept sine, dual sine

Rate range

Sine 0.5 Hz to 1 MHz

Square, ramp, triangle 0.5 Hz to 100 kHz

Resolution 0.5 Hz

Accuracy Same as timebase

LF out

Output Internal1 or internal2. Also provides monitoring of

internal1 or internal2 when used for AM, FM, or ΦM.

Amplitude 0 to 3 V

peak

, into 50 Ω (nominal)

Output impedance 50 Ω (nominal)

Swept sine mode:

(frequency, phase continuous)

Operating modes Triggered or continuous sweeps

Frequency range 1 Hz to 1 MHz

Sweep rate 0.5 Hz to 100 kHz sweeps/s, equivalent to

sweep times 10 us to 2 s

Resolution 0.5 Hz (0.5 sweep/s)

Wideband AM

External modulation inputs

(Ext1 & Ext2)

Simultaneous modulation

Internal modulation source

1. Internal2 is not available when using swept sine or dual sine modes.
