- Various test probes and cables.
- Carrying Case
The WILTRON Model 9041 Transmission Level and Return Loss Measuring Set fulfills or exceeds the requirements of Western Electric Specification KS 20501 for Through and Terminal Balance of all classes of telephone offices. The Model 9041 incorporates in one instrument the means to mea- sure transmission level, receive frequency response, echo return loss and singing return loss on 4-wire or 2-wire, 600 ohm or 900 ohm circuits. These features permit measurements of loss and balance that meet Bell System, USITA and CCITT specifications.
Measuring Features
The Model 9041 Measuring Set provides transmission level measure- ments from +12 dBm to 48dBm on both 600 and 900 ohm incoming and outgoing trunks over a bandpass of 200Hz to 5kHz. return loss (ERL) and singing return loss (SRL) (high and low) measurements from -10dB (10dB return gain) to 50dB are provided. Trans-hybrid loss correction of up to 30.8dB in 0.2dB steps is provided for 4-wire return loss measurements. Unused transhybrid correction ranges may also be used to correct +7 or -16dB point levels at VFPB's (voice frequency patching bays) or to extend return loss range beyond 50dB on 4-wire circuits. The meter scale and panel controls are marked in red for level measurements and black for return loss measurements.
