Tektronix TM504, DM501A, PS503A, DM502A,DC503A, PG506A


Tektronix TM504 Chassis, DM501A Digital Multimeter, PS503A Power Supply, DM502A Autoranging DMM, DC 503A Frequency Counter, and the PG506A Calibration Generator
Tektronix TM504 4 Slot Power Chassis
The TM504 is a 4 slot power chassis. It weighs 21 pounds unloaded. The TM504 Power Module Mainframe accepts up to four single width TM 500 plug-ins. Each TM504 comes equipped with front panel switch, tilt bail, and a handle. The right hand compartment is a high-power compartment.
Tektronix DM 501A Digital Multimeter
The DM 501A Digital Multimeter measures dc and ac voltage, dc and ac current, resistance, dB, and temperature. The DM 501A gives 4 digits of readout resolution, all with 0.05% accuracy and true RMS capability. True RMS allows accurate measurement of distorted waveforms. Readout in dB is useful when making critical audio and communication measurements. Fast accurate temperature measurements to 240°C come from the Tektronix P6601 (not included) platinum-film temperature sensing probe. The P6601 reaches 90% of final reading in 1.5 seconds.
* 0.05% DC Voltage Accuracy
* Seven Functions including Temperature and dB
Tektronix PS 503A Dual Power Supply
The Tektronix PS 503A Dual Power Supply provides 0 to 20V at 400mA (1A in high power compartment) and +5V at 1A Independent + and - controls, or dual tracking voltage control. The PS 503 provides three outputs: +5 V at 1 A , 0 to +20 V, or 0 to -20 V at 1 A (in high-power compartment of TM504 or TM506) or 400 mA (in the tm503 standard mainframe compartment) Independent + and -controls, or dual tracking voltage control. Tektronix PS 503A provides dual floating variable 20V supplies, plus a fixed 5-V, 1_A supply. The PS 503A features superior tracking, over voltage protection, and remote resistance programing of voltage. When operated in the high power compartment of a TM 504, TM506, or TM5006 mainframe, the PS503A can provide up to 1 A from both of the 20V supplies. A 0 to 40V variable supply with up to 1 A of current can be configured by grounding one of the two outside terminals of the variable supplies. The two variable supplies can be set individually, then varied in a tracking mode with a signal control.
* Dual tracking Voltage Controls
* 0 to 20 V at 1 A (in a high Power Compartment)
* Remote Resistance Programing
Tektronix DM 502A 3 1/2 digit DMM
The Tektronix DM 502A 3 1/2 digit multimeter measures six functions with push button convenience. Autoranging, in all modes except current, makes it exceptionally easy to use without having to select ranges. The instrument measures dc and ac voltage, dc and ac current, dB, and resistance. It provides true RMS measurements in all AC modes, which provides more accuracy with distorted, noisy or other non-sinusoidal ac waveforms. The resistance mode also offers Hi-Lo voltage (2v to 0.2v) modes. This user-selectable feature allows in-circuit ohms measurements without turning on diode or transistor junctions. The high-voltage mode allows you to test semiconductor junctions for forward and reverse resistances. The DMM 502A Digital Multimeter measures dc and ac voltage and current, dBm, dBV, resistance, and temperature. The ac functions are true RMS responding. The ranges for dc voltage, ac voltage, dBm, dBV, and resistance are automatically or manually selected as desired. The current and temperature ranges are manually selected.
* DC Voltmeter - Ranges 200mV, 2V, 20V, 200V, and 1000V
* AC Voltmeter (TRUE RMS) Ranges 200mV, 2V, 20V, 200V, 500V
* Decibels (dB) - TRUE RMS - Ranges -10dB, +10dB, +30dB, and +50dB
* Resistance Ranges 200W, 2kW, 20kW, 200kW, 2000kW, and 20MW
* DC Ammeter Ranges 200µA, 2mA, 20mA, 200mA, and 2000mA
* AC Ammeter (TRUE RMS) Ranges 200µA, 2mA, 20mA, 200mA, and 2000mA
* Temperature -55deg C to 200deg C
The DC 503A Universal Counter/Timer
The DC 503A Universal Counter/Timer is designed to operate in a TM 500-series power module. The instrument has two input channels, CH A and CH B, each with 125 MHz capability. Each channel has separate triggering level, triggering slope, attenuator, and coupling mode controls. The DC 503A has eight measurement functions: FREQUENCY A, PERIOD B, WIDTH B, TIME A-B, RATIO A/B, EVENTS A DURING B, TOTALIZE A, and TIME MANUAL. All of the modes except FREQUENCY A, TOTALIZE A, and TIME MANUAL have the capability of averaging the selected measurement over a range of 1 to 10(exp 8) times the input signal. The output of the internal signal shaping ciruits can also be monitored via front panel connectors. These shaped signal outputs are useful in setting the triggering points on complex waveforms. Measurement results are displayed in an eight digit LED readout. The decimal point is automatically positioned and leading zeros are blanked. Single annunciators (LEDs) are used to indicate register overflow, active gating interval, and the frequency or time units associated with the measurement being made.
Tektronix PG506A Calibration Generator
THE PG506A PROVIDES THREE MODES OF SQUAREWAVE OUTPUTS, SELECTABLE DC OUTPUTS,, AND A VARIABLE-AMPLITUDE OUTPUT WITH FRONT PANES DIGITAL INDICATION OF OSCILLISCOPE DEFLECTION ERROR.
