To Set Frequency/Period
Frequency is one of the most important parameters of basic waveforms. For different
instrument models and waveforms, the setting ranges of frequency are different. For
detailed information, please refer to “Frequency Characteristics” in “Specifications”.
The default frequency is 1kHz.
The frequency displayed on the screen is the default value or the frequency
previously set. When the instrument function is changed, if this frequency is valid
under the new function, the instrument will still use this frequency; otherwise, the
instrument would display prompt message and set the frequency to the frequency
upper limit of the new function automatically.
Press Freq/Period to highlight “Freq”. At this point, use the numeric keyboard to
input the desired frequency value and then select the desired unit from the pop-up
menu.
 The frequency units available are MHz, kHz, Hz, mHz and μHz.
 Press this softkey again to switch to period setting. At this point, “Period” is
highlighted.
 The period units available are sec, msec, μsec and nsec.

To Set Amplitude/High Level
The amplitude setting range is limited by the “Impedance” and “Freq/Period” settings.
Please refer to “Output Characteristics” in “Specifications”. The default value is
5Vpp.
The amplitude displayed on the screen is the default value or the amplitude
previously set. When the instrument configuration (such as frequency) is changed, if
this amplitude is valid, the instrument will still use this amplitude; otherwise, the
instrument would display prompt message and set the amplitude to the amplitude
upper limit of the new configuration automatically. Users can also use “High Level” or
“Low Level” to set the amplitude.
Press Ampl/HiLevel to highlight “Ampl”. At this point, use the numeric keyboard to
input the desired amplitude value and then select the desired unit from the pop-up
menu.
 The amplitude units available are Vpp, mVpp, Vrms, mVrms and dBm (invalid in
HighZ).
 Press this softkey again to switch to high level setting. At this point, “HiLevel” is
highlighted.
 The high level units available are V and mV.
Users can also use the direction keys and knob to set the parameter value: use the
direction keys to move the cursor to select the digit to be edited and then rotate the
knob to change the number.
KEY POINTS:
1. How to convert the amplitude in Vpp to the corresponding value in
Vrms?
Method:
Vpp is the unit for signal peak-peak value and Vrms is the unit for signal
effective value. The default unit is Vpp. Press · in the numeric board to
quickly switch the current amplitude unit.
Note:
For different waveforms, the relation between Vpp and Vrms is different. The
relation of the two units is as shown in the figure below (take sine waveform
as an example).
DG1000Z User’s Guide
2-5
RIGOL
Chapter 2 Front Panel Operations
Vamp
Vrms=0.707Vamp
Vpp=2Vamp
According to the figure above, the conversion relation between Vpp and Vrms
fulfills the following equation:
Vpp = 2 2Vrms
For example, if the current amplitude is 5Vpp, press · in the numeric
keyboard and select “Vrms” to convert 5Vpp to the corresponding value in
Vrms. For sine waveform, the converted value is 1.768Vrms.
2. How to set the amplitude of waveform in the unit of dBm?
Method:
1) Press CH1|CH2 to select the desired channel.
2) Press Utility  ChannelSet  OutputSet  Imped to select “Load”
and set proper load value using numeric keyboard.
3) Select the desired waveform and press Ampl/HiLevel to highlight
“Ampl”. Use the numeric keyboard to input the desired value and then
select dBm from the pop-up menu.
Note:
dBm is the unit for signal power absolute value and the conversion relation
between dBm and Vrms fulfills the following equation:
Vrms 2
1
=
dBm 10lg(
×
)
R
0.001W
In this equation, R represents the channel output impedance value and it must
be a certain value, so the unit dBm is not available when the output
impedance is “HighZ”.
For example, if the current output impedance is 50Ω and the amplitude is
1.768Vrms (5Vpp), press · in the numeric keyboard and then select “dBm”
to convert the amplitude value to the corresponding value in dBm. The
converted value is 17.9601dBm.

To Set Offset/Low Level
The DC offset setting range is limited by the “Impedance” and “Ampl/HiLevel”
settings. Please refer to the “Output Characteristics” in “Specifications”. The
default value is 0VDC.
The DC offset voltage displayed on the screen is the default value or the offset
previously set. When the instrument configuration (such as impedance) is changed,
if this offset is valid, the instrument will still use this offset; otherwise, the instrument
would display prompt message and set the offset to the offset upper limit of the new
configuration automatically.
Press Offset/LoLevel to highlight “Offset”. At this point, use the numeric keyboard
to input the desired offset value and then select the desired unit from the pop-up
menu.
 The DC offset voltage units available are VDC and mVDC.
 Press this softkey again to switch to low level setting. At this point, “LoLevel” is

Align Phase
DG1000Z series dual-channel generators enable to align the phases of the two
channels. Pressing down this softkey will re-configure the two channels and enable
the generator to output with specified frequency and start phase.
For two signals whose frequencies are the same or in multiple, this operation will
align their phases. For example, assume a sine waveform (1kHz, 5Vpp, 0°) is
outputed from CH1, while another one (1kHz, 5Vpp, 180°) from CH2. Use an
oscilloscope to sample and display the two signals, you will see that the waveforms
shown on the oscilloscope do not always have a phase deviation of 180°. At this
point, press Align Phase on the generator and the waveforms shown on the
oscilloscope will have a phase deviation of 180° without any adjustment of the start
phase of the generator.

To Output Harmonic
DG1000Z can be used as a harmonic generator to output harmonic with specified
order, amplitude and phase. It is usually used in the test of harmonic detector device
or harmonic filter device. This section introduces how to configure the generator to
output harmonic.
Overview
According to Fourier transform, time domain waveform is the superposition of a
series of sine waveforms as shown in the equation below:
f (t ) = A1 sin(2πf1t + ϕ1 ) + A2 sin(2πf 2 t + ϕ 2 ) + A3 sin(2πf 3t + ϕ 3 ) + ......
Generally, component with f1 frequency is called fundamental waveform, f1 is
fundamental waveform frequency, A1 is fundamental waveform amplitude, ϕ1 is
fundamental waveform phase. The frequencies of the other components (called
harmonics) are all integral multiples of the fundamental waveform frequency.
Components whose frequencies are odd multiples of the fundamental waveform
frequency are called odd harmonics and components whose frequencies are even
multiples of the fundamental waveform frequency are called even harmonics.
DG1000Z can output up to 8th harmonic. After selecting CH1 or CH2, press Sine 
Harm to select “On” and press Harmonic Para to enter the harmonic setting menu.
You can set the type of harmonic, specify the highest order of harmonic and set the
amplitude and phase of each order of harmonic. If you want to set various
parameters of fundamental waveform, please set the parameters of Sine.
After finishing harmonic parameters setting, press Output1 and the backlight turns
on, the instrument outputs the specified harmonic from the corresponding output
terminal.

Modulation
DG1000Z can output modulated waveform from a single channel or from two
channels at the same time. Modulation is the process of modifying certain
parameters (such as amplitude, frequency, phase and etc.) of the carrier waveform
signal according to the change of the modulating signal. The carrier waveform can be
Sine, Square, Ramp, Arbitrary waveform (except DC) or Pulse (only in PWM). The
modulating waveform can be from internal or external modulation source. DG1000Z
supports AM, FM, PM, ASK, FSK, PSK and PWM.
Amplitude Modulation (AM)
For amplitude modulation (AM), the amplitude of the carrier waveform varies with
the instantaneous voltage of the modulating waveform.
To Select AM Modulation
Press Mod  Type  AM to enable AM function. When Mod is enabled, Sweep or
Burst will be disabled automatically (if enabled currently).
To Select Carrier Waveform Shape

DC). The default is Sine.
 Press the front panel key Sine, Square, Ramp or Arb (you need to press
Select Wform in the arbitrary waveform setting interface to select the desired
arbitrary waveform) to select the desired carrier waveform shape.
 Pulse, Noise and DC could not be used as carrier waveform.
To Set Carrier Waveform Parameters
The different settings of various parameters (frequency, amplitude, DC offset, start
phase and etc.) of the carrier waveform will influence the AM modulated waveform.
For different carrier waveform shape, the ranges of the various parameters are
different (the ranges are related to the model of the instrument used and the carrier
waveform currently selected. See “Specifications” for details). For all carrier
waveform shapes, the default values are 1kHz frequency, 5Vpp amplitude, 0VDC
offset and 0° start phase.

Carrier Waveform Suppression
DG1000Z supports the normal amplitude modulation and double sideband
suppressed carrier (DSB-SC) amplitude modulation. In the normal amplitude
modulation, the modulated waveform contains carrier waveform components.
Because carrier waveform components carry no information, the modulation is less
efficient. In order to improve the modulation efficiency, the carrier waveform
components are suppressed on the base of the normal amplitude modulation. At this
time, all modulated waveform carry information. This method is called double
sideband suppressed carrier modulation. By default, DG1000Z works in the normal
amplitude modulation and users can enable the double sideband suppressed carrier
modulation through pressing the menu key DSSC and selecting “On”.

Sweep
DG1000Z can output sweep from a single channel or from dual channels at the same
time. In sweep mode, the generator outputs signal variably from the start frequency
to stop frequency within the specified sweep time. DG1000Z supports linear, log and
step sweep modes, allows users to set start hold, end hold and return time, supports
internal, external or manual trigger source, and can generate sweep output for Sine,
Square, Ramp and arbitrary waveform (except DC).
To Enable Sweep Function
Press Sweep at the front panel to enable the sweep function (the backlight of the
key turns on), and Mod or Burst function will be automatically disabled (if currently
enabled). The instrument will generate the sweep waveform from the corresponding
channel (if currently turned on) according to the current configuration. You can also
reset the sweep parameters. Please refer to the introduction in the following text for
details.
Start Frequency and Stop Frequency
Start frequency and stop frequency are the upper and lower limits of the frequency
for frequency sweep. The generator always sweeps from the start frequency to the
stop frequency and then returns back to the start frequency.
 Start Frequency < Stop Frequency: the generator sweeps from low frequency to
high frequency.
 Start Frequency > Stop Frequency: the generator sweeps from high frequency
to low frequency.
 Start Frequency = Stop Frequency: the generator outputs with a fixed
frequency.
When sweep mode is enabled, press Start/Center to highlight “Start”. Notice that
the “Stop” in Stop/Span key will also be highlighted at the same time. Use the
numeric keyboard or direction keys and knob to input the desired frequencies. By
default, the start frequency is 100Hz and the stop frequency is 1kHz. Different sweep
waveform corresponds to different start frequency and stop frequency range.
 Sine: 1μHz to 60MHz
 Square: 1μHz to 25MHz
 Ramp: 1μHz to 1MHz
 Arb: 1μHz to 20MHz
The generator will renewedly sweep (according to the current new configuration)
from the specified “start frequency” after start or stop frequency is changed.

Center Frequency and Frequency Span
You can also set the frequency boundaries of frequency sweep through center
frequency and frequency span.
 Center Frequency = (|Start Frequency + Stop Frequency|) / 2
 Frequency Span = Stop Frequency – Start Frequency
When sweep mode is enabled, press Start/Center to highlight “Center”. Notice
that the “Span” in Stop/Span will also be highlighted at the same time. Use the
numeric keyboard or direction keys and knob to enter the desired frequency values.
By default, the center frequency is 550Hz and the frequency span is 900Hz. Different
sweep waveform corresponds to different center frequency and frequency span
range and the center frequency and frequency span are interrelative.
Define the minimum frequency of the waveform currently selected as Fmin , the
maximum frequency as Fmax and Fm = ( Fmin + Fmax ) / 2 .


The range of center frequency is from Fmin to Fmax and the parameters for
different waveforms are as follows.
Sine: 1μHz to 60MHz
Square: 1μHz to 25MHz
Ramp: 1μHz to 1MHz
Arb: 1μHz to 20MHz
The range of frequency span is influenced by the center frequency.
Center frequency < Fm : the range is ±2× (center frequency – Fmin );
Center frequency ≥ Fm : the range is ±2× ( Fmax – center frequency).
Take sine as an example. Fmin is 1μHz, Fmax is 60MHz and Fm is about 30MHz.
If the center frequency is 550Hz, the frequency span range is ±2×(550Hz–1μHz) =
±1.099999998kHz; if the center frequency is 55MHz, the frequency span range is
±2×(60MHz–55MHz) = ±10MHz.
The generator will renewedly sweep (according to the current new configuration)
from the specified “start frequency” after center frequency” or frequency span is
changed.
TIP:
In large-scale sweep, the amplitude characteristic of the output signal might
change.

Sweep Type
DG1000Z provides Linear, Log and Step sweep types and the default is Linear
sweep.
Linear Sweep
In linear sweep type, the output frequency of the instrument varies linearly in the
way of “several Hertz per second”. The variation is controlled by “Start Frequency”,
“Stop Frequency” and “Sweep Time”.
When Sweep is enabled, press Type to select “Linear”. A straight line is displayed
on the waveform on the screen, indicating that the output frequency varies linearly.
Figure 2-7 Linear Sweep
Log Sweep
In Log Sweep type, the output frequency of the instrument varies in a logarithmic
fashion, that is, the output frequency changes in the way of “octave per second” or
“decade per second”. The variation is controlled by “Start Frequency”, “Stop
Frequency” and “Sweep Time”.
When Log Sweep is enabled, users could set the following parameter:
Start Frequency ( Fstart ), Stop Frequency ( Fstop ) and Sweep Time ( Tsweep ).
The function prototype of Log Sweep:
Fcurrent = P T
Fcurrent is the instantaneous frequency of the current output. P and T could be
expressed as shown below by the above-mentioned parameters:
P = 10 stop start sweep
T = t + lg( Fstart ) / lg( P)
lg( F
/F
) /T
Wherein, t is the time from the start of the sweep and its range is from 0 to Tsweep .
When Sweep is enabled, press Type to select “Log”. An exponential function curve
is displayed on the waveform on the screen, indicating that the output frequency
changes in a logarithmic mode.

return time is modified.
Mark Frequency
The sync signal output from the [CH1/Sync/Ext Mod/Trig/FSK] connector
(corresponds to the channel at the front panel) at the rear panel always changes
from low level to high level at the start of each sweep. The sync signal changes from
high level to low level at the center frequency point when “Mark” function is disabled
or at the specified mark frequency point when “Mark” function is enabled.
When Sweep is enabled, press Mark to select “On” and use the numeric keyboard
or direction keys and knob to modify the mark frequency. The default value is 550Hz
and the available range is limited by “Start Frequency” and “Stop Frequency”.

once the mark frequency is modified.
KEY POINTS:
For step sweep (the sweep points determined by the start frequency, stop
frequency and step number respectively are f1, f2, ……, fn, fn+1……), if the mark
frequency setting is one of the sweep points values, the sync signal is TTL high
level at the start of the sweep and will change to low level at the mark frequency
point. If the mark frequency setting is not any one of the sweep points values, the
sync signal will change to low level at the sweep point which is closest to this mark
frequency.
Start Hold
Start hold is the duration that the output signal outputs with the “Start Frequency”
after the sweep starts. After the start hold, the generator will output with varying
frequency according to the current sweep type.
When Sweep is enabled, press Start Hold and use the numeric keyboard or
direction keys and knob to change the Start Hold. The default value is 0s and the
available range is from 0s to 500s.

Store and Recall
DG1000Z can store the current instrument state and user-defined arbitrary
waveform data in internal or external memory and recall them when needed.
DG1000Z also could interconnect with RIGOL oscilloscope which supports USB-TMC
seamlessly and rebuilt and output the waveform data collected by the oscilloscope
losslessly.
Storage System
DG1000Z can store the current instrument state and user-defined arbitrary
waveform data in internal or external memory and recall them when needed.
DG1000Z provides an internal non-volatile memory (C Disk) and an external memory
(D Disk).
1. C Disk: provide 10 storage locations for state files and 10 storage locations for
arbitrary waveform files. Users can store instrument states and arbitrary
waveform files (created by users or downloaded via remote commands) to C
Disk and copy the files in USB storage device to C Disk.。
2. D Disk: available when USB storage device is detected by the USB Host
interface at the front panel.
Users can store state files and arbitrary waveform files to D Disk and the
number of the files can be stored is determined by the storage space of USB
storage device. The Txt files, Csv files and Bmp files stored in the USB storage
device can also be readed.
Press Store (the key backlight goes on) at the front panel to enable the Store/Recall
function and open the Store/Recall interface as shown in the figure below.

Note: DG1000Z can only identify files of which filenames consist of Chinese
characters, English letters, number and underscore. If other characters are used to
name the file or folder, the name might be displayed in the store and recall interface
abnormally.
File Type
Press Store  File Type to select the desired file type. The file types available
include State File, Arb File, Txt File, Csv File, Bmp File and All File.
1.
State File
Store the instrument state in internal or external memory in “*.RSF” format. At
most 10 instrument states can be stored in internal memory.
The state file stored includes waveforms selected, frequency, amplitude, DC
offset, duty cycle, symmetry, phase and modulation, sweep, burst parameters
used of the two channels and counter parameters as well as utility parameters
and system parameters under the Utility menu.
2.
Arb File
Store the user-defined arbitrary waveform in internal or external memory in
“*.RAF” format. At most 10 arbitrary files can be stored in internal memory.
In arbitrary waveform file, the voltage values corresponding to each waveform
point are stored in binary data format. In sample rate edit mode, if the points is
set to Sa, the arbitrary waveform file only contains Sa points of which the
voltage all are user-set values. In period edit mode, if the points is set to Sa, the
voltage of the first Sa points are user-set values and the voltage from the
(Sa+1)th point to the 8192th point are low level. The voltage value of each
point takes 2 bytes (16 bits). The lower 14 bits are used to represent voltage
and the higher 2 bits are unused. Therefore the format of binary data is from
0x0000 to 0x3FFF. Wherein, 0x0000 corresponds to the low level of the arbitrary
waveform and 0x3FFF corresponds to the high level of the arbitrary waveform.
The stored arbitrary waveforms can be read by each model of DG1000Z series.
Besides, the arbitrary waveforms stored in USB storage device can be opened
and edited by data editing tools (such as WinHex or UltraEdit etc.) via computer.

KEY POINTS:
Sync Signals of Various Waveforms:
1.
Basic Waveform
1)
The frequency of the basic waveform is less than or equal to 100kHz or
the sync delay is not 0:
The sync signal is a Square with 50% duty cycle and the same frequency
as that of the basic waveform. When ouputting the first waveform point,
the sync signal is TTL high level.
2)
The frequency of the basic waveform is greater than 100kHz:
 Sine and Ramp: the sync signal is a Square with 50% duty cycle.
 Square and Pulse: the sync signal is a Square with variable duty cycle
which varies with the duty cycle of the output signal.
Take 0V voltage (or the DC Offset of the basic waveform) as the
reference, the sync signal is TTL high level when the corresponding value
of the output signal is greater than the reference. When the frequency of
the basic waveform is less than or equal to 30MHz, the sync signal has the
same frequency as the basic waveform. When the frequency of the basic
waveform is greater than 30MHz, the frequency of the sync signal is (the
basic waveform frequency÷2n). Wherein, n represents the frequency
dividing coefficient and it is equal to 1 when the frequency of the basic
waveform is greater than 30MHz and less than or equal to 60MHz.
3)
Noise: there is no sync signal output.
2.
Harmonics
For harmonics, the sync signal is a square with 50% duty cycle and the same
frequency as that of the fundamental waveform. When ouputting the first
waveform point, the sync signal is TTL high level.
3.
Arbitrary Waveform
For arbitrary waveform, the sync signal is a square with 50% duty cycle and
the same frequency as that of the arbitrary waveform. When ouputting the
first waveform point, the sync signal is TTL high level.

Chapter 2 Front Panel Operations
Modulated Waveform (the sync delay is invalid)
1)
When internal modulation source is selected:
the sync signal is a square with 50% duty cycle.
 For AM, FM, PM and PWM, the frequency of the sync signal is the
modulating frequency.
 For ASK, FSK and PSK, the frequency of the sync signal is the
modulating rate.
2)
When external modulation source is selected:
The terminal is used to accept the external modulation signal and there is
no sync signal output.
Sweep Waveform (the sync delay is invalid)
1) When internal or munual trigger source is selected:
 If “Mark” is disabled:
The sync signal is a square with 50% duty cycle. The sync signal is
TTL high level at the start of the sweep and changes to low level at
the mid-point of the sweep. The frequency of the sync signal is the
reciprocal of the sum of the specified sweep time, return time, start
hold and end hold times.

If “Mark” is enabled:
For linear and log sweep, the sync signal is TTL high level at the start
of the sweep and changes to low level at the mark frequency.
For step sweep (the sweep points determined by the start frequency,
stop frequency and step number respectively are f1, f2, ……, fn,
fn+1……), if the mark frequency setting is one of the sweep points
values, the sync signal is TTL high level at the start of the sweep and
will change to low level at the mark frequency point. If the mark
frequency setting is not any one of the sweep points values, the sync
signal will change to low level at the sweep point which is closest to
the mark frequency.
2)
2-86
When external trigger source is selected:
The terminal is used to accept the external trigger signal and there is no
sync signal output.
DG1000Z User’s Guide
RIGOL
Chapter 2 Front Panel Operations
6.
Burst Waveform(the sync delay is invalid)
1)
When internal or munual trigger source is selected:
 Infinite burst: the sync signal is the same as that of the basic
waveform.
 N cycle burst: the sync signal is TTL high level at the start of the
burst and will change to TTL low level after the specified number of
cycles finished. For the sync signal, the frequency is the reciprocal
of the Burst Period and the duty cycle is
Carrier Period * Cycles / Burst Period.
 Gated burst: the terminal is used to accept the external modulation
signal and there is no sync signal output.
2)
When external trigger source is selected:
The terminal is used to accept the external trigger signal and there is no
sync signal output.
Output Set
1. Output Polarity
Set the output signal on the [CH1] connector as normal or inverted. Waveform
inversion is relative to the offset voltage. Press Utility  Channel Set 
Output Set  Output to select “Normal” or “Invert”. The default is “Normal”.
The waveform is normally outputted in “Normal” mode and is inverted before
outputted in “Invert” mode. For example, the waveform of the first half period of
the cycle is positive in “Normal” mode and negative in “Invert” mode, as shown
in the figure below.

2. Output Impedance
The output impedance setting influences output amplitude and DC offset. The
instrument has a 50Ω fixed serial output impedance for the [CH1] connector at
the front panel. If the actual load is different from the specified value, the
voltage level displayed would not match the voltage level of the device under
test. To ensure correct voltage level, the load impedance setting must match the
actual load.
Press Utility  Channel Set  Output Set  Imped to select “HighZ” or
“Load”. The default is “HighZ”. If “Load” is selected, use the numeric keyboard to
set specific impedance value. The default is 50Ω and the available range is from
1Ω to 10kΩ. Impedance setting will be displayed on the screen.
The generator will adjust the output amplitude and offset voltage automatically
once the impedance setting is changed. For example, the current amplitude is
5Vpp. At this point, change the output impedance from 50Ω to HighZ and the
amplitude displayed on the screen will double to 10Vpp. If the output impedance
is changed from HighZ to 50Ω, the amplitude will reduce to half of the previous
value (2.5Vpp). Notice that only the displayed values change with the parameter
and the real output from the generator does not change.
3. Output Mode
Set the output mode of the [CH1] connector as normal or gated. In gated mode,
the output state of the [CH1] connector is controlled by the signal from the
[CH1/Sync/Ext Mod/Trig/FSK] connector at the rear panel. When “Gated”
is selected, press “Polarity” to select “Pos” or “Neg”.
 Positive: the [CH1] connector ouputs signal when the gated signal is high
level.
 Negative: the [CH1] connector ouputs signal when the gated signal is low
level.
4. Range
Press Utility  Channel Set  Output Set  Range and select “Auto” or
“Hold”.
 Auto: the generator selects the best settings for the output amplifier and
attenuator automatically.
 Hold: disable the automatic optimization, which can eliminate the
discontinuation of the waveform caused by the relay switch when changing
the amplitude but may affect the amplitude accuracy.

DG1000Z supports frequency, amplitude and phase couplings. Users can set the
frequency deviation (frequency ratio), amplitude deviation (amplitude ratio) or phase
deviation (phase ratio) of the two channels. When coupling is enabled, CH1 and CH2
are mutual base source. When the frequency, amplitude or phase of one channel (as

Channel coupling is only available when both the waveforms of the two
channels are basic waveforms including Sine, Square, Ramp and Arbitrary
waveform (except DC).
If the sum (or product) of the frequency, amplitude or phase of CH1 and the
deviation (or ratio) set exceeds the upper limit of frequency, amplitude or
phase of CH2 or the value of the frequency, amplitude or phase of CH2 minus
(or is divided by) the deviation (or ratio) set is below the lower limit of
frequency, amplitude or phase of CH1, the generator will adjust the frequency,
phase or amplitude of the later channel to avoid parameter overrange.
When the phase of the one channel is changed, the phase (phase displayed on

Clock Source
DG1000Z provides an internal 10MHz clock source and accepts external clock source
from the [10MHz In/Out] connector at the rear panel. It can also output clock
source from the [10MHz In/Out] connector for other devices.
Press Utility  System  Clk Src to select “Int” or “Ext”. The default is “Int”. If
“Ext” is selected, the instrument will detect whether a valid external clock signal is
input from the [10MHz Out/In] connector at the rear panel. If no valid clock
source is detected, the prompt message “Not detect a valid external clock!” would be
displayed and the clock source would be switched to “Int”.
You can synchronize two or more instruments by setting the clock source. When two
instruments are synchronized, the “Align Phase” function can not be used. “Align
phase” is only applicable to be used to adjust the phase relation between two output
channels of the same instrument and can not be used to change the phase relation
between the output channels of two instruments. Of course, you can change the
phase relation between two instruments by changing the “Start Phase” of each
channel.
Sync methods for two or more instruments:
 Synchronization between two instruments:
Connect the [10MHz In/Out] connector of Generator A (“Internal” clock) to
the [10MHz In/Out] connector of Generator B (“External” clock) and set the
output frequencies of A and B as a same value to realize synchronization
between two instruments.
 Synchronization among multiple instruments:

MAC Address
MAC (Media Access Control) address, also called hardware address, is used for
defining the position of the network device. For a generator, the MAC address is
always unique. It is always used to identify the instrument while assigning IP address
for instrument. MAC address (48 bits, namely 6 bytes) is usually expressed in
hexadecimal format, such as 00-14-0E-42-12-CF.
VISA Descriptor
VISA (Virtual Instrument Software Architecture) is an advanced application
programming interface developed by NI (National Instrument) for communications
with various instrument buses. It uses the same method to communicate with
instruments regardless of the types of the instrument interfaces (GPIB, USB,
LAN/Ehternet or RS232). The GPIB, USB, LAN/Ethernet or RS232 instrument which
wants to communicate with VISA is called “resource”.
VISA descriptor is the resource name and describes the accurate name and location
of the VISA resource. If LAN interface is currently used for communication with the
instrument, the VISA descriptor is TCPIP0::172.16.3.33::INSTR.

means output without gain and “X10” means to amplify the signal 10 times and
then output.
3.
Output
Select “Normal” or “Invert” output mode for the signal output from the PA. Pay
attention to distinguish it with “Output Polarity” of DG1000Z.
4.
Offset
Turn “On” or “Off” the output deviation for the output from the PA. When “On” is
selected, use the numeric keyboard or direction keys and knob to set deviation
value. The available range is from -12V to 12V and the default value is 0V.

Configure network parameters
1) DHCP mode:
If the network supports DHCP, the DHCP server in the network assigns
network parameters (IP Address, Subnet Mask, Gateway and DNS) for the
generator automatically.
2)
Auto IP mode:
When the network doesn’t support DHCP, the DHCP mode of the generator
is disabled or the generator is connected to the PC directly, the generator
selects Auto IP mode and acquires the IP address from 169.254.0.1 to
169.254.255.254 and subnet mask 255.255.0.0 automatically.
3)
Manual IP mode:
Enable the Manual IP mode and disable the DHCP mode as well as the Auto
IP mode to set the network parameters manually.
If the generator is connected to the PC directly, set the IP Addresses,
Subnet Masks and Gateways for both of the PC and the generator. The
Subnet Masks and Gateways of the generator and PC must be the same and
the IP Addresses of them must be within the same network segment (for
details, refer to the TCP/IP protocal). An example is shown in the table
below.

Note[1]:
Full power bandwidth refers to the maximum frequency when the power amplifier can generate AC
output with the maximum possible amplitude and without distortion.
Full power bandwidth
FPB =
SR
2πVmax
SR: Slew Rate (output slew rate)
Vmax: the maximum amplitude without distortion that the amplifier can output
Note[2]:
Definition of Slew Rate: input a large step-function signal into the amplifier, the output slope of the
signal is saturated to a constant at a certain position. This constant is called the Slew Rate of the
amplifier.
Note[3]:
The specifications above are all specifications under 25℃. The range of the environment
temperature for PA1011 is from 0℃ to +35℃ and when the environment temperature is greater
than 35℃, it is recommended that users reduce the output power and the working frequency of
PA1011.
