Digital multimeter
Weston has designed the model 6100 3 1/2-digit LCD display audio response digital multimeter. The unit features a five range audio response function which allows go-no-go testing to performed with out paying attention to the display and has instantaneous response.
The unit also features five functions: ac/dc volts, ac/dc current and resistance.The 1600 is priced at $139.
15MHz dual-trace scopes
Telequipment's two new 15MHz scopes, the D1015 and D1016, feature 8 x 10 cm CRTs and color-coded front panels, 5mV to 20V/div vertical sensitivity, and triggering capabilities including TV mode. The D1016 also features full sensitivity X-Y, differential, X5 vertical magnification and a variable time base.
Strength meter
The model LFC-944B VHF/UHF field strength meter from Leader measures levels of 20 to 120 dBµV on VHF channels. A built-in attenuator up to 80dB of attenuation in 10dB steps. The unit features VHF channel selection with accurate detented.
The unit features VHF channel selection with accurate detented tuning and continuous UHF tuning, and is battery powered. The suggested price is $512 complete.
Scope probes
Model SP100, replacement 1X/10X scope probe, is available now from Test Probes. A ground reference switch position enables the scope input to be grounded at the probe tip. This feature serves as a positive means of trace identification, and allows a zero voltage to be selected from the probe. The cable has a flexible and rugged center conductor, strain relief at connector and probe head fittings, and a BNC-pin diameter tip. For the 10X function, a 10-60pF trimmer range is provided.
The SP100 comes complete with sprung hook, trimmer tool, BNC adaptor, IC tip, and insulating tip for $36.
30MHz scope
The B&K-Precision model 1479 features an internal 160nS signal-delay line, minimum visible delay of 12nS. Rise time is 11.7nS or less. Other features include a 10-position vertical attenuator which covers 5mV to 5V per cm at an accuracy of +3 %, 20 calibrated sweep positions from 0.2 usec/cm to 0.5 sec/cm (X5 magnification increases sweep speed to 40 ns/cm), and TTL-compatible intensity modulation. The 1479 has fully regulated power supplies and is designed to maintain accuracy over a 105-130VAC range. Optional accessories include a rack mounting kit and protective cover. The unit lists at $1099.
Microprocessor-controlled DVM
Sencore is now marketing a microprocessor-controlled auto-ranged DVM. Basically a 4 1/2-digit instrument, the DVM-56 Microranger can be changed to a 3 1/2 or 2 1/2-digit DVM with the push of a button. The DVM-56 features a do voltage accuracy of .075 %, plus or minus five counts, with 15 M-ohm input impedance. Three automatic peak-to-peak ac voltage ranges to 2KV at 100KHz, also are featured. Three automatic dB ranges to 1KV at 20KHz from -43 to +62dB, 1mV into 600-ohm, extends the use of the DVM to audio frequencies. The DVM-56 is priced at $695.
VHF signal generator
The Leader LCG-138 VHF signal generator is a calibrated source of test signals for CATV and MATV systems. The unit provides calibrated outputs on two high and two low VHF channels at accurate levels from 60 to 10 dBuV in 10dB steps. It is battery powered. The LCG-138 sells for $244.
