Delayed sweep scope
B&K-Precision has introduced the model 1530 30MHz scope with delayed sweep. It offers five ranges of time base delay from 1ps to 100ms. Vertical input sensitivity is 2mV per division. The 1530 features variable hold-off, front panel X-Y operation, differential measurement capability, and algebraic addition and subtraction of two vertical input signals. The unit operates on 115 or 230 Vac.
The 1530 includes probes and manual for $1340.
RF wattmeter
A new series of RF wattmeters has been announced by Bird with the 4381 Power Analyst, a 9-mode digital directional RF wattmeter for power levels from 1/10W to 10,000W, and from 1/2 to 2300MHz.
CW or FM power, both forward or reflected, is displayed in watts or dBm. VSWR is calculated continuously and indicated, as is dB return loss.
The unit is priced at $590.
Hand-held multimeter
The Heath IM-2215 hand-held portable digital multimeter features alternating high-to-low resistance test voltage, built-in references for in-the-field calibration, and a 3 1/2-digit LCD display. Five ranges allow ac voltage measurement to 750V rms and dc voltage to 1000V. Ac and dc current flow is measurable to 2000mA. The unit is battery-operated and battery condition is monitored continuously.
The IM-2215 is priced at $94.95.
Temperature probe
The Hickok TP-20 probe measures temperatures from-55° to 150°C or-67° to 302°F. The probe operates up to 500 hours on one 9V battery, and features a battery test position.
The TP-20 probe and the LX-303 DVOM are available at a total price of $115.
Dual-trace scope The Gould 0S253 is a compact portable 12MHz dual trace scope that weighs 15 lbs. Case size is 5 1/4"x12"x16 1/2"; the display area is 8cm x 10cm CRT.
Capacitance sub box
Cincinnati Electrosystems' model 315 capacitance box is an accurate and inexpensive instrument for troubleshooting and maintenance use. This compact unit substitutes any of 21 capacitance values ranging from 100pF to 10pF. It measures 4" x 2 7/8" x 1 9/16", and is priced at $20.95.
Isolation transformer
Sencore has designed the PR57 ac Powerite 400W isolation transformer. The unit features an automatic safety check, probe and one-button leakage check. Ac voltage is variable from 0 to 140V. A 2 % recessed 6-inch meter is used to monitor ac volts, current and watts. The unit sells for $375.
Production test oscilloscope
Leader Instruments LBO-5800 production oscilloscope system will allow the operator to select up to 32 preset configurations of oscilloscope controls to view waveforms at up to eight test points in a unit under test. In operation the operator attaches up to eight probes to the unit under test and uses a single button to cycle through up to 32 tests. All vertical, horizontal and trigger controls are automatically set to pre-programmed positions during each test.
The system consists of four components: the LBO-5810 programmable oscilloscope, the LPC-5811 memory/control unit, the LPC-5813 input selector and the LPC-5812 programmer. A single test station including programming capabilities is $5995.
