high quality shielded cables to this instrument. High quality shielded cables typically are braid and foil types that have low impedance connection to shielded connectors at both ends.

eaning

Inspect the instrument as often as operating conditions require. To clean the exterior surface, perform the following steps:

1. Remove loose dust on the outside of the instrument with a lint-free cloth. Use care to avoid scratching the display.

2. Use a soft cloth dampened with water to clean the instrument. Use an aqueous solution of 75% isopropyl alcohol for more efﬁcient cleaning.

CAUTION. To avoid damage to the surface of the instrument, do not use any

abrasive or chemical cleaning agents.

CAUTION. Avoid getting moisture inside the unit during external cleaning. Use

only enough cleaning solution to dampen the cloth or swab.

NOTE. When connecting a cable, be sure to distinguish the input connector from

the output connectors to avoid making the wrong connection.

The instrument input and output connectors are ﬂoating inputs/outputs.

WARNING. To avoid personal injury due to electric shock, do not apply voltages

in excess of 42 Vpk to any BNC connector ground or to the chassis ground.

Floating ground

Since the common (input and output channel common) of the arbitrary function generator is electrically isolated from the chassis ground (the instrument chassis and ground line of the AC connector), you can make a ﬂoating connection between the instrument and othe r equipment.

All the signal output connectors are connected to the common ground, and the remote interface connector is connected to the chassis ground.

WARNING. T

ﬂoating voltage and the output voltage of the instrument does n ot exceed 42 Vpk. Do not touch the center of the BNC while the equipment is in use.

CAUTION. The maximum rated voltage between the chassis ground and common

ground is 42 Vp-p (DC + peak AC). When the potential voltage between the chassis ground and common ground goes over 42 Vp-p, the internal protective circuit will be activated to protect the circuits. However, higher voltage may cause the internal circuits in the instrument to be damaged.

When a potential voltage exists between the chassis ground and common ground, a short circuit from output to ground causes the instrument internal fuse to open and th Tektronix Service Support.

Triggered Burst Mode. Aspeciﬁed number (burst count) of waveform cycles are output when the instrument receives a trigger input from the internal trigger source, an external trigger source, a remote command, or the Manual Trigger button.

Gated Burst Mode. The instrument outputs a continuous waveform when an effective gate signal is applied externally, when the Manual Trigger button is depressed, when a remote command is applied, or during 50% of the selected internal trigger interval.

The following example describes how to generate a double pulse using the burst mode.

1. Select Pulse as an output waveform and then push the front-panel Burst button.

2. Conﬁrm that 1-Cycle, N-Cycles, or Inf-Cycles is s e lected, which means triggered burst mode is enabled.

Adjusting Parameters of Two Channel Signals (dual-channel models only)

Phase

The AFG3000 series uses phase continuous method to change frequency. When you change a frequency of a channel, it will affect the phase relationship between the two channels.

For example, the instrument is generating a 5 MHz sine waveform for both CH1 and CH2 and the phase is adjusted between the two channels. If you change the CH2 frequency to 10 MHz and then return it to 5 MHz, the CH2 phase does

ot return to its initial condition. To adjust the phase relationship between the
