SECTION 1 GE N ERAL INFORMATION

1-1. General

The TR5821/5822/5823/5823H are compact, inexpensive universal counters with the capabilities comparable to medium-scale counters. These are the

It became possible to process data with a self-diagnostic function and

various operations (by using TR1644). Since GPIB, BCD (TTL)

output, and analog output (D/A converter) are available, these

equipments can support various system.

TR5821 is a universal counter that can measure frequencies of up to

120 MHz, and can display results in arbitrary form with TR1644 (an extra-cost option).

The TR5822 has the same functions as the TR5821 plus a built-in GPIB interface, and the functions of the TR5823 include an ultrahigh-frequency measurement (1.3 GHz) and a burst signal measurement in addition to the

functions of the TR5821.

The TR5823H is provided with the high-stability oscillator (aging rate:

5 x l0 “8/day) as a standard feature plus the capabilities of the TR5823. * The TR5823 described in this manual also includes the functions of the

TR5823H.

1-1

1-2. Caution

1. With POWER ON, self-check is automatically initiated; any failure will pro duce an error message “E01, E07, E10” for about 2s. When POWER is ON after RESET ON, check of panel switches is performed (See instruction manual 3-3-3 for details).

2. When a panel switch is pressed, function is selected and the instrument is in the standby state; when released, operation is strarted in the TOT. mode, totalize operation continues but display is held while the ON/OFF switch is being pressed (GATE lamp on); when released (GATE lamp off), totalized result is displayed.

3. Though selectable by function selector switch, 4 ^ position on TR 5821/5822 is not used. Move to any other position.

4. In case of frequency measurements (FREQ.B/TR5821, TR5822,

TR5823, TR5823H), when the rapid switching of input frequency happen, the tim ing of switched frequency may cause, the measurement time to get longer.

OPERATIONS

3-1. Preparation and Cautions Before Use

3-1-1. Inspection

After receiving this unit, check it for any damages that may have occurred during transit, especially for damage of panel switches and terminals. Should any damage be found or if the unit does not operate as specified, contact your nearest ADVANTEST representative.

3-1-2. Storage

For long-term storage, place the unit in a vinyl cover or cardboard box and store it at low-humidity out of direct sunlight.

3-1-3. Transportation

To transport this unit, use the original packing. If the packing has been

discarded, pack it as follows: (1) Wrap the unit in a vinyl. (2) Place the unit in a cardboard box having walls at least 5 mm thick. Place

packing of 40 mm or thicker under, all around, and over the unit.

(3) After covering the unit with packing, fit the accessories in the box and

place packing over them. Close the cardboard box, then secure the box with packing tape.

3-1-4. General Cautions Before Use

(1) Power supply

The power voltage has been set at factory; it is indicated above the power cable on the rear panel. Use a power supply of 100 V ac±10%, or 120/220 V ac ±10%, 240 V ac +4%, —10% at a frequency of 50 Hz to 400 Hz. Check that the POWER switch is set to STBY before connecting the power cable to the power source.

(2) Power cable

The power cable has a 3-prong plug; the round prong in the center is for ground. When connecting the plug to the power receptacle via an adap

ter, connect the wire leading out of the adapter to ground. (See Figure 3-1.)

3-1

Adapter

Fig. 3-1 Power cable plug and adapter

R ep lacem ent of a fuse

A fuse is installed into the outlet on the rear panel. The check or replacement of the fuse should be done as follows. (Applicable

fuses are shown in Table 3-1.) To change an AC line voltage, pull the voltage selector out with

a pair of long-nose pliers and so on, and then set the AC line

voltage. You can see the selected AC line voltage on the face of the voltage selector.

(4) Operating environment

Use this unit in a location free from dust, direct sunlight, and corrosive

gases. The environmental conditions for use are a temperature of 0°C

to +40°C and a relative humidity of 85% or lower.

(5) Shock

This unit has a crystal oscillator; so do not subject it to strong mechani cal shock.

(6) STBY

When the power cable plug is connected to a power receptacle, the

reference oscillation circuit starts operation and the unit enters the standby state; measurement is enabled immediately after the unit is POWERed ON. Since the reference oscillator is not temperature com pensated, the frequency fluctuates as shown in Figure 6-2 after POWER ON, even if the unit has been set to STBY with the power cable plug connected, to a power receptacle.

(7) Selection of time base signal

Either the external or internal time base signal can be used by operating the INT. STD OUT./EXT. STD IN. switch on the rear panel. INT. STD OUT. selects the internal time base signal and outputs it. EXT. STD IN. allows input of an external time base signal (1 Vp.p to 10Vp.p, 500£2,

10 MHz).

the operation of this unit (without changing the functions).

@ RMT

The lamp goes on when this unit is in the remote state. In this case, no operation is made when a panel switch is pressed. (For GPIB remote control)

@ AC 100 V

Indicates the available voltage. Use 100/120/220 V ac at ±10%, or 240 V a c +4%,-10%.

@ T0.4A

Indicates the rating of the fuse in use. Use a 0.4 A slow-blow fuse for

100/120 V ac;use a 0.2A slow-blow fuse for 220/240 V ac.

Trimmer for adjusting the internal reference oscillator.

@ INT. STD OUT./EXT. STD IN.

Internal reference oscillator and external reference signal selector switch.

INT. STD OUT. selects the internal reference oscillator and outputs the frequency value at © . When EXT. STD IN. is selected, the external reference signal fed to © operates this unit.

GPIB connector is used to connect this unit to the GPIB interface for externally controlling function, gate time/multiplier, hold of this unit.

3-3. Basic Operating Procedure

This section explains how to use each function of the TR5820 series. Check the model name before operation. For convenience, the TR5823 is used in illustrations.

3-3-1. Self-diagnostics Function (CHECK)

(g)(2) ® ©

----------------------------------Fig. 3-4 Self-check routine

Check 3-1-4. “General Cautions Before Use” before powering the unit.

(7) POWER ON starts the self-diagnostics function which checks the micro

processor, two LSIs, and existence of the reference signals. When no error is found, all segments and indicator lamps (except the GATE lamp and decimal point) go on (about 2 seconds) for checking. Then, this unit is initialized to:

FUNCTION GATE T IM E

Other functions . . . .OFF

(2) 10.000 MHz is displayed and the GATE lamp blinks. (3) Display readout changes as below with each press of GATE TIME (o)

10.000 MHz

Press (o) again to set GATE TIME to 10 ms.

CHECK 10 ms

--------------------------------

(4) Press [°««] to light the lamp within the switch. Turn the MASK TIME

control to see that the display changes approximately 100 /is to 100 ms. Press [T«« 1 to deactivate the masking function.

(3) Press 1 to light the lamp within the switch;the GATE lamp goes off. (6) Press RESET; the GATE lamp blinks once. (7) Press 1 to release the hold; the GATE lamp starts blinking again.

3-3-2. Error Messages

An error message is displayed when an error is found during self-diagnostics and when an arithmetic operation or data setting error is found. A self diagnostics error message is displayed for about 2 seconds, and the operation shifts to CHECK (some errors may cause it inoperative). When an arithmetic operation or data setting error message is displayed, the operation stops. Table 3-1 lists the error messages; the cause of each message may be found in any other place than those listed below.
