4. Installation
4.1 Unpacking and inspection
Every care is taken in the choice of packing materials to ensure that your equipment will reach you in perfect
condition.
Unpack the equipment and check for external damage to the case, sockets, keys etc. If damage is found, notify the
carrier and your sales representative immediately.
The standard accessories supplied with the instrument are as described in the Section 1.
4.2 Preparation for Operation
Under no circumstances should users touch any of the front terminals, unless the are first assured that no dangerous
voltage is present.
Power Input
The recess power input plug, power fuse and line voltage indicator are contained in an integral module in the rear
panel.
Power cable
The detachable supply cable, comprising of 3-core PVC cable permanently moulded to a fully-shrouded 3-pin socket,
fits in the power input plug recess and should be fitted fully.
The supply lead should be connected to a grounded AC power receptacle ensuring that the ground lead is
connected, to avoid electrical shock.
Line voltage
The PeakTech 4110 is operative within the line voltage ranges 230 V AC ± 10 %, 50 or 60 Hz, for F/G, F/C and DPS.
The DMM section of the instrument is powered by a single 9 Volt battery (Type NEDA 1604 or 6F22). The battery
annunciator appears on the LCD display, when the battery voltage drops to certain limits. Continued operation with a
flat battery will lead abnormal readings.
Bench Mounting
This instrument is fitted with four rubber feet. It is intended to stand flat on a bench, located at least 30 cm of free
space at the rear.
In addition, 2 plastic tilt-stand are provided next to the front rubber feet, to facilitate the viewing angle of the
instrument from the bench level.
5. Operating the PeakTech 4110
Prior to operating this instrument, it is important that it has been correctly installed as detailed in the Section 4.
The operating instructions are devided into four major groups; Universal Counter (U/C). Function Generator (F/G),
DC Power Supply (DPS) and Digital Multimeter (DMM). - 23 -

• Turn on the Power switch of DPS
• Turn on the Power switch of U/C located on the rear panel. In this case, all segments, PASS-ALL and UC-1300
shall be displayed as a self test.
• Set the display Option key (28) at U/C position.
• Set the Gate time switch (4) at 1 S position.
• Set the Channel Select Switch (3) at Channel A position.
• Set the Data-Hold Switch and the Attenuation Switch at the pushed-out position. Now, "GATE" "0.0000000"
"MHz" is lit up at frequency LED display.
5.1.3 Features
Channel Select Switch (3)
The Channels A and B will cover your measurement of the frequency from 5 Hz up to 100 MHz with auto range. The
Channel C will cover your measurement of the frequency from 100 MHz up to 1.3 GHz.
Gate Time Switch (4)
For a better resolution in your measurement, your selection for a proper gate time is advisable. The following table
will help you refer to the optional frequency resolution.

Gate Time 100 mS 1 S 10 S
Low Range 10 Hz 1 Hz 0,1 Hz
High Range 100 Hz 10 Hz 1 Hz
Data-Hold Switch (5)
Upon activation of this mode, a read-out on the LED display will be captured and remained even after disconnecting
the test connector from a measuring point.
Attenuation Switch (2)
If input signal is greater than 700 mV, set the Attenuation Switch at the pushed-in position with connecting the input
signal to channel A only.
The triggering sensitivity of the input signal will be decrease by 1/10 (-20 dB) and reduce errors.
Reset Switch (6)
If you want to return to the normal frequency mode from the arithmetic modes, set FREQ switch at the pushed-in
position.
5.1.4 Mesuring the output frequency generated by F/G
If you want to measure the output frequency being measured by the function generator, set the display option key
(28) at F/G position. - 25 -

Because the maximum output frequency of F/G is 10 MHz, the range select channel should be set at CH-A which can
read the frequency ranging from 5 Hz to 100 MHz.

5.2.5 Features
Voltage Controlled Frequency
Output frequency can be varied with an external input from the VCF input Terminal (16).
For 0 ~ 10 V DC VCF input voltage, the frequency is changed by 1:2, depending upon activation of the frequency
range select switch (26). To operate the VCF function, turn the frequency control knob (24), fully CCW, and connect
the external voltage to the VCF input terminal.
Amplitude Control
The maximum amplitude of output voltage is more than 20 V under the open load, but it is reduced by half (50 %)
under the 50 Ωload or 600 Ωload. The amplitude output voltage can be varied continuously with operating the
Amplitude control knob (19), in the range of -20 dB. If the Amplitude Control Knob is pulled out, the output signal is
set to the -20 dB fixed.
OFF-SET Control
The DC level of output signal can be varied continuously with operating the OFF-SET control knob (20) in the range
of ± 10 V. To adjust the DC level, pull out the OFF-SET control knob then, turn slowly CW (positive volt) or CCW
(negative volt). If the OFF-SET control knob is pushed in, there is no DC level, but only AC voltage exists in the
output signal.
Symmetry Control
The duty cycle of output signal can be varied continuously with the symmetry control knob (21) in the range of 1:3 or
3:1. To adjust the symmetry of the waveforms, pull out the symmetry control knob, then turn it slowly to the CCW
direction. The following table shows such variations under this mode.
Note: After setting the symmetry control knob (21), the output frequency will decrease and the operator should re-
adjust the frequency.
Sweep Control
To enable the internal frequency to sweep, pull out the sweep width control knob (22). The width of the frequency
sweep can be varied continuously in the range of 100 : 1. To maximize the sweep width, set the frequency control
dial (24) fully to the CCW direction, and turn the sweep width control knob fully to CW.
To adjust the rate of frequency sweep, turn the sweep rate control knob slowly CW or CCW or linear frequency
sweep. Logarithmic frequency sweep mode is operative with by pulling the sweep rate control knob (23).
TTL Output
The TTL level signal output is available at the TTL output terminal (17). The TTL output can drive 30 unit loads in the
HIGH state and 20 unit loads in the LOW state. One unit load in the HIGH state is defined as 40 µA and 1.6 mA in the
LOW state.
